Israel's military and one of its soldiers are no longer "friends" after the gunner posted details of an impending West Bank raid on his Facebook page.

Militants bombarded Baghdad's Green Zone with rockets on Sunday, taking advantage of the cover of a blinding dust storm to launch one of the heaviest strikes in weeks on the fortified compound. The strikes appeared to defy a renewed call for a ceasefire by Shi'ite cleric Moqtada al-Sadr, which has seen many of his masked gunmen leave the streets of the Sadr City slum.

The Israeli Prime Minister, Ehud Olmert, on Sunday ruled out ceasefire negotiations with the Islamist movement Hamas and said his military was fighting a "true war" against armed groups in Gaza. He warned of further Israeli military strikes in the days ahead which he said were intended to prevent Palestinian militants from firing makeshift rockets into Israel.
