Palestinian security forces in the Gaza Strip have destroyed three illegally-built homes of senior Palestinian officers - as part of what the Palestinian Authority says is a new anti-corruption campaign.

A spokesman for the Palestinian Interior Ministry says bulldozers destroyed the homes built on illegally seized public land. He said the violators were informed ahead of Monday's action, and that the buildings were not occupied.

Palestinian leader Mahmoud Abbas, who succeeded the late Yasser Arafat in January, has been under pressure to end growing chaos in the Gaza Strip and West Bank, and to root out corruption among senior Palestinian officials and commanders of security forces.
