None
Libya's revolutionary forces say they have stepped up a siege around Muammar Gaddafi's hometown of Sirte to wear down his loyalist forces inside.
The fighters have set up new roadblocks and checkpoints and posted snipers at key spots on Sunday.
The move comes after a heavy push by the fighters into the edge of the downtown that failed to dislodge Gaddafi's men inside Sirte on Saturday. Seven fighters were killed and 150 were wounded in fierce street battles with Gaddafi's men. (AP)
