1848 GMT: Though the battle for Abu Salim is far from over, the opposition fighters, assisted by a NATO airstrike, have started to go house to house, cleaning out snipers and taking prisoners. Gunfights continue.
More than 30 men believed to be fighters loyal to Muammar Gaddafi have been killed at a military encampment in central Tripoli and at least two were bound with plastic handcuffs, indicating they had been executed.
A Reuters correspondent counted 30 bodies riddled with bullets in an area of the Libyan capital where there had been fighting between Gaddafi forces and rebels.
1636 GMT: The "we were all wrong and Qaddafi is winning" alert - Muammar Qaddafi has given yet another audio address. Here are some select quotes, courtesy of the BBC, Reuters, and the Twitterverse:
Qaddafi called on his loyalists to "fight and destroy" the rebels, he said that he enjoys the support of a "sweeping majority," and he urged the "youth of Tripoli" to " fight them everywhere, street street, zanga zanga (alley by alley). Purify Tripoli." Qaddafi closed with his signature,"Forward, forward, forward" closing.
