New photos have been released from the burned-out American consulate in Benghazi, Libya, that show what remains of the damaged buildings in the light of day. The pictures show a compound gutted by fire and scarred by graffiti and looting. There have also been some new details this morning about what exactly happened during the assault.

According to various reports, about 20 armed men stormed the compound with guns and rocket-propelled grenades during the night. Ambassador Christopher Stevens, foreign service officer Sean Smith, and other employees were moved to a second building to seek safety, but their location was discovered (possibly exposed by the Libyan guards that were supposed to protect them) and that building came under attack as well. There were initial reports that the men tried to escape in a car that was then struck by an RPG, but given that Stevens apparently died of asphyxiation and had no other injuries, it's likely that they were still inside building when they were overcome by smoke.

One "counter-extremism think tank" believes that attack may have been premeditated — meant as al-Qaeda revenge killing to coincide with the September 11 anniversary — and not related to the incendiary anti-Muslim movie at all, like the protests in Cairo. CNN reporters also say that "U.S. sources" agree with that assessment and that the attackers used the peaceful protest as a "diversion" to reach the embassy, but that  the ambassador was not specifically a target.

One other note: Some pictures circulated online this morning showing Libyans carrying the unconscious body of Stevens after the attack. There was speculation that might have been the protesters who killed him, but President Obama said in his remarks that friendly Libyans carried Stevens to the hospital, where doctors tried to revive him for close to 90 minutes.
