Israel demanded suspected militants surrender, but said those who gave themselves up were not the men they wanted

Explosions later rocked Mr Arafat's compound, destroying buildings all around him (AP)

The siege continued on Friday, with troops surrounding the compound and digging a trench round Mr Arafat's office building

On Saturday, Israeli troops finally entered the main office building, heavily damaged but still standing

Troops asserted their control by exchanging a Palestinian flag for an Israeli one on the rooftop of the remaining building
