A roadside bomb killed 11 Iraqi troops and two injured others Saturday. The attack against the Iraqi soldiers took place near Adhaim, about 60 miles north of Baghdad, Iraqi officials said. Following the blast, the Iraqi convoy came under intense small arms fire, officials added.
Elsewhere, a U.S. base at Mosul's airport was attacked by mortar fire Saturday, wounding two US soldiers, the U.S. Army said.
On Friday, three American troops died in a traffic accident south of Baghdad, and the US military said another soldier died of wounds suffered the previous day when his vehicle was hit by a rocket in Ramadi, 70 miles west of the capital.
Meanwhile, Al-Jazeera TV has aired a videotape and statement in which the kidnappers of four Christian peace activists threatened to kill the hostages - two Canadians, an American and a Briton - unless all prisoners in U.S. and Iraqi detention centers are released by Dec. 8.
