A homicide car bomb exploded Friday on a bridge overlooking the home of President Jalal Talabani (search), killing three of his guards, a spokesman for Iraq's largest Shiite Muslim group said.

The attack occurred about 8 p.m. on Al-Hussein Bridge over the Tigris River (search), according to Haitham al-Husseini, spokesman for the Supreme Council for the Islamic Revolution in Iraq.

He said several people were wounded, including some civilians.

The Supreme Council (search) has offices in the area, and leaders of the organization also live in the Jadriyah district.

It was unclear if Talabani, a Kurd, was in the house at the time of the explosion. Guards are posted on the bridge because it overlooks the president's house and leads to an area where several key government figures have homes.
