Three U.S. Marines killed in western Iraq

BAGHDAD (Reuters) - Three U.S. Marines were killed in action in Anbar province in western Iraq on Monday, the U.S. military said in a statement on Wednesday.

Anbar is the heartland of the Sunni insurgency against Prime Minister Nuri al-Maliki's Shi'ite-led government and U.S. forces. It is the deadliest area in Iraq for U.S. soldiers.

The deaths of the three soldiers brought to at least 37 the number of U.S. troops killed in Iraq since the start of October.

The U.S. military said on Tuesday it killed seven insurgents in an air strike on a building in Ramadi, capital of Anbar, after U.S. troops came under "extremely heavy fire".

Three U.S. soldiers were killed in Anbar on Sunday.
