Saturday was a particularly deadly day in and around Baghdad. Eight U.S. soldiers were killed by explosions or gunfire in different parts of the capital, raising the fatality count to 30 in the last six days, according to The Washington Post.
U.S. military officials say powerful roadside bombings are occurring more frequently as more American troops are deploying on the streets of Iraq, particularly in the capital. U.S. officials say many of the materials used to make the bombs and much of the know-how for building them are being imported from neighboring Iran.
In the deadliest incident Saturday, four U.S. soldiers were killed in northwest Baghdad when a roadside bomb—known as an improvised explosive device, or IED—exploded near their vehicle during combat operations, according to a military statement. An Iraqi interpreter was wounded in the attack.
