Egyptians awaiting news of relatives who were aboard an Egyptian ferry that sank in the Red Sea last week have set fire to the office of the firm that owned the boat.
Police used tear gas to drive away the people, who had attacked the office of the As Salam maritime company outside the Egyptian Red Sea port of Safaga.
Relatives have been gathered at the port entrance since Friday, when the Salam 98sank with nearly 1,400 people on board.
The crowd, desperate for information about survivors, swelled to more than 1,000 over the weekend but dropped to about 300 on Monday, witnesses said.
The authorities have deployed hundreds of riot police to block the entrance to the port, where the ferry had been due to dock. It had been sailing from Saudi Arabia, and most of the passengers were Egyptian workers.
Television footage showed a crowd of men hurling chairs, filing cabinets and air conditioning units out of the first floor office, piling them up in front of the building and starting the fire, shouting and chanting as they did so.
In the port of Hurghada, about 40 miles to north, a crowd outside the local hospital became angry when a line of police officers displayed photographs of those who had drowned. The crowd broke through the security barriers erected in front of the hospital, but did not manage to get through the gates and enter the building.
It appeared as if the relatives wanted to see the bodies of their loved ones in the hospital morgue.
More than 400 survivors have been rescued and 195 bodies recovered but about 800 people are still missing following the tragedy.
Relatives of the missing have protested against what they see as rough treatment by the government. They have also been angered by survivor accounts of the ferry continuing its voyage for several hours after a fire had started below deck.
