Update: body not yet found
A press conference is under way in Los Angeles. LAPD police commander Andrew Smith corrects an earlier report from the Riverside County police chief that a body had been found and identified in the cabin. He says no body has been found, and indeed the fire in the cabin is so hot that officers have not been able to enter the cabin.
Updated at 11.13pm ET
The police chief of Riverside county, Sergio Diaz, whose officers were involved in the search, has confirmed that the body found inside the cabin was that of the fugitive former police officer Christopher Dorner, according to the Press-Enterprise of Riverside. A statement from the San Bernardino county sheriff's department is expected soon.
Body found in cabin
There are numerous reports that a body has been found in the cabin where a man believed to be fugitive Christopher Dorner was holed up.
The Associated Press reported that the body was "charred". A fire at the cabin was left to burn by officials for over two hours this evening.
It is likely to be some time before the body is officially identified but authorities had said earlier that they believed the man in the cabin was Dorner.
The Los Angeles police department has scheduled a news conference for midnight ET.

• Authorities believe fugitive Christopher Dorner was inside a Big Bear log cabin as it was engulfed by flames on Thursday afternoon. A spokeswoman forSan Bernardino sheriff's department said investigators believed the man was inside the building as a fire raged for more than two hours.
• One deputy sheriff is dead, another injured after an exchange of gunfire with a man believed to be Christopher Dorner. Authorities are yet to name either deputy, but said the second was expected to live after undergoing surgery at Linda Loma hospital.
• LA mayor Antonio Villaraigosa has said the city's "hearts and prayers" are with the family of the deputy shot and killed today. In a news conference he added that "none of us can imagine" what the families threatened by Dorner "have had to go through".
• Dorner had allegedly tied up two occupants of a different cabin in Big Bear before stealing their car early on Thursday. The victims called police, which began the localised hunt for Dorner, who had been on the run since killing a retired police chief's daughter and her fiance on 3 February.
Man did not emerge from cabin fire
Adding to Cindy Bachman's press conference earlier, Associated Press reports that the man believed to be fugitive ex-cop Christopher Dorner never came out of the Big Bear mountain cabin.
Citing an anonymous law enforcement official AP says that a single shot was heard inside the cabin before it was engulfed in flames.
LA mayor Antonio Villaraigosa speaks to media from downtown LA.
“Our hearts and prayers are with the San Bernardino deputy who was shot and killed today. Our prayers are with their family and with the people of San Bernardino, with the sheriffs department of that county.”
Villaraigosa says he will not comment on the specifics of what happened this afternoon and the ongoing situation in Big Bear.
“I want to say something about the men and women and the children who were targeted," he says. "None of us can imagine what they've had to go through, what their children have had to go through because of the threats of Christopher Dorner.”
Cindy Bachman from San Bernardino county sheriff's department has just been interviewed by local news channel KCAL9.
"We do believe [Dorner] is still inside," Bachman says. She is asked if the man could have escaped the building.
"I only have information that the investigators there have given me and they believe he is inside."
She said authorities have brought in powerful lights as darkness begins to fall.

"I have not been advised that there are any hostages involved in this current situation," Bachman says.

She says she does not know who started the fire. She said she did not know when authorities might attempt to enter the cabin.
Bachman is asked about injuries to other officials. "I'm only aware of our two deputy sheriffs that were shot," she says.

The LA Times has spoken to the owner of the cabin where Christopher Dorner has apparently taken shelter.
Candy Martin said she was "in a state of shock" after seeing her vacation cabin in Big Bear surrounded by police. The cabin is in a cluster of seven cabins close to Highway 38. Dorner had reportedly stolen a vehicle from a different cabin earlier in the day.
Local media are reporting 200 police officers have surrounded the cabin.
From the Times:
Candy Martin was sitting down for an episode of "Walking Dead" with her daughter when she turned on the news and saw her Big Bear-area vacation cabin surrounded by police amid reports of a shootout involving the wanted fugitive Christopher Dorner.
Her son called police to let them know she was the owner of the 85-year-old cabin, one in a cluster of seven cabins that she owns along California 38 near the community of Seven Oaks. Martin talked to police, telling them the cabins were supposed to be empty Monday and had no cable, phone or Internet service. There were also no firearms inside, she said.
"I was basically in a state of shock," Martin said.
Martin said her sisters spent time in the main cabin over the weekend. She said she wasn't surprised Dorner was able to make his way inside -- the old cabins "are easy to get into," she said.
"It's quite shocking," she said. "I mean, it's good and bad news. If it is him, I hope that they catch him and this whole horrible thing is put to rest. At the same time, who wants this happening on their property?"
Updated at 6.42pm ET
The Guardian's Rory Carroll quotes LAPD commander Andrew Smith during the news conference as saying there may be no immediate attempt to storm the cabin where Dorner is believed to be cornered.
"Our first priority is the safety of the community in that area.. once that area is locked down we'll let the San Bernadino swat team go in there and do what they do best," Smith said.
LAPD commander: 'It's time to turn yourself in'
Los Angeles police department commander Andrew Smith has just held a brief press conference in downtown LA.
He urged Dorner to give himself up to police, "stop the bloodshed" and face the justice system.
"Enough is enough. It's time to turn yourself in. It's time to stop the bloodshed. It's time to let this event and let this incident be over," Smith said.
He said LAPD officers were still following up on the 1,045 clues they had received from members of the public. The LAPD has also sent resources to San Bernardino airport, Smith said, where they were waiting to be called upon by the San Bernardino county sheriff's department.
Smith said he could not confirm that people had been taken hostage by Dorner. "I can't confirm that anyone was held hostage at this time."
The commander reiterated that police had asked media not to show live broadcasting images from the Big Bear area as it could "put our officers at a disadvantage".
"The best thing for [Dorner] now would be to surrender so we can take him into custody and he can face the criminal justice system," Smith added.

A CBS LA reporter was close to the area where gunfire was exchanged earlier this afternoon. The news channel continued to broadcast live as shots rang out.
Here's an extract from the transcript of the conversation between reporter Carter Evans and anchor Sandra Mitchell, as Evans apparently gets caught up in midst of a police manoeuvre. Evans has been broadcasting since this incident.
CARTER: We’re trying to, we’re not moving from our vehicle, because this is a very fluid situation. We’re staying here, we don’t want to get caught in the crossfire ourselves.
UNIDENTIFIED: Hey you! Come here!
UNIDENTIFIED: You! Come here! [Unintelligible]
UNIDENTIFIED: Hey! Get the f— out of here now!

Confirmed: two police officers airlifted to hospital
San Bernardino county sheriff’s department has issued a statement confirming that two police officers have been airlifted to hospital after an “exchange of gunfire between law enforcement and the suspect”.
Dorner has fled into the forest, according to police, and “barricaded himself in a cabin”, the department said in an email.
The sheriff's department said deputies responded to an address on Club View Drive after a call out regarding a stolen vehicle. The person who contacted police said the suspect bore a similarity to Dorner.
The suspect appears to have left the vehicle and continued on foot before exchanging fire with police.
Here is the full statement from San Bernardino county sheriff's department:
On Tuesday, February 12, 2013 at 12:22 p.m, deputies working the Big Bear area search for Christopher Dorner responded to the 1200 block of Club View Dr. for a reported stolen vehicle. The reporting party said the suspect took their vehicle and described the suspect as looking very similar to Dorner. Deputies immediately began a search on the ground and from the air for the vehicle.
The vehicle was located at Hwy. 38 and Glass Rd. The suspect fled into the forest and barricaded himself inside a cabin. A short time later there was an exchange of gunfire between law enforcement and the suspect. Sheriff’s SWAT is onscene.
Two law enforcement officers are being airlifted to a local hospital with unknown injuries.
The hunt for Christopher Dorner, a former police officer accused of two murders in California, appears to have narrowed with reports that the fugitive former police officer has been involved in a shootout with law enforcement officers on Tuesday afternoon.
Two deputies with the San Bernardino sheriff's department were shot and wounded in Big Bear, north-east of Los Angeles.
Local news reports said Dorner had broken into a home, tied up two people and stolen a pickup truck. Dorner was then confronted on a highway by fish and game wardens before fleeing on foot. He is now holed up in a cabin, according to the San Bernadino's sheriff's office.
News outlets, including CBS Los Angeles, aired the sounds of gunfire and shouting in live broadcasts from the Big Bear area.
Dorner is accused of targeting law enforcement officers and their families in three revenge-driven killings.
He had posted a lengthy online "manifesto" explaining agrudge against the LAPD, which fired him in 2008. It named dozens of people; since then, many officers have been given 24-hour protection.
On February 3 he is alleged to have shot dead Monica Quan, 28, the daughter of a retired police captain, and her fiancé Keith Lawrence, 27.
Four days later he allegedly ambushed two other officers at a traffic light, killing one, Michael Crain, 34, a veteran, and wounding the other, a trainee.
The net now appears to be closing in on Dorner. We will have live updates as the story develops.
