The U.S. military in Iraq says two American soldiers have been killed in separate roadside bombings in Baghdad.
A coalition spokeswoman says the bombings took place Tuesday while U.S. and Iraqi forces were carrying out security operations aimed at quelling the sectarian violence in Baghdad.
Seven-hundred more U.S. troops arrived Tuesday in nearby Diyala province to crack down on the sectarian fighting.
Also Tuesday, Iraqi's Shi'ite Prime Minister Nouri al-Maliki made an unannounced visit to the western city of Ramadi, the heart of the Sunni insurgency in restive al-Anbar province.
Mr. Maliki met with tribal leaders, local government officials and commanders of Iraqi and U.S. security forces. He said Iraq's government is working to solve the many problems in the province.
It was Mr. Maliki's first visit to Ramadi since taking office nearly one year ago.
In other news, an official with the party of Iraqi President Jalal Talabani says the Iraqi leader is to return to Iraq today (Wednesday) from Jordan. Mr. Talabani has been undergoing treatment for exhaustion and dehydration since late February. He is in his early-70s.
