Attempts to talk to militants amid fears for hostages
At least 24 people have died in clashes in the past week after gunbattles broke out between security forces and supporters of hard-line clerics who have tried to impose Taliban-style rule in the capital.
After a botched commando raid on the high-walled compound at the weekend, President Pervez Musharraf assigned ex-premier Chaudhry Shujaat Hussain to try to negotiate a peaceful end to the stand-off.
