More Western targets hit in Iraq
Four people were killed and 20 injured Friday in a grenade attack on a shop in Baghdad.
Religious extremists attacked the shop as it was reportedly selling alcohol on the Muslim day of rest during the holy month of Ramadan.
Elsewhere, in Baghdad, the Sheraton and Palestine hotels and the Iraqi Oil Ministry were hit by rocket attacks.
Large numbers of contractors and journalists have been based at the hotels.
Several rockets were launched from an improvised launcher hidden on donkey carts selling oil.
There was also a blast outside the office of a British-based mine clearance agency in the northern Iraqi city of Arbil.
A truck loaded with petrol was detonated near the offices of the Mine Action Group. Minor damage was reported but no casualties.
Adnan al-Mufti, an official of the Patriotic Union of Kurdistan, blamed the explosion on supporters of Saddam Hussein.
It was the second explosion in less than 48-hours in the Kurdish-controlled area.
On Thursday, a truck bomb exploded near a Kurdish party office in Kirkuk, killing five people and wounding 30.
