Vice President Joe Biden urged rival Iraqi politicians Sunday to end months of delays and select new leaders for their wobbly democracy, predicting a peaceful transition of power even as suicide bombers struck government centers in two major cities.
The attacks in Mosul and Ramadi underscored persistent fears that insurgents will exploit Iraq's political uncertainty to stoke widespread sectarian violence. Four people were killed and 25 injured in the two blasts that occurred hundreds of miles apart.
The twin explosions on the Fourth of July illustrated the vexing nature of the U.S. involvement in Iraq and its efforts to nudge the country toward stability and democracy.
At least five mortar rounds also fell in the Green Zone late Sunday when Biden was there, said Iraqi police officials. The Green Zone is the sprawling protected area in the heart of Baghdad that is home to the U.S. Embassy as well as the Iraqi parliament and prime minister's office.
There were no reported casualties, said the officials, who did not want to be identified because they were not authorized to speak to reporters. Mortars and rockets are periodically fired into the Green Zone but rarely result in casualties or damage.
On his fifth trip to Iraq since he was elected, Biden sat down separately with Prime Minister Nouri al-Maliki, a Shiite who is struggling to keep his job after his party lost the March 7 election, and his chief challenger, former premier Ayad Allawi.
