BAGHDAD (AP) -- A rocket or mortar attack Saturday at a U.S.-run detention facility in southern Iraq killed at least six detainees and wounded 50, the military said. No American casualties were reported.

The attack was launched against the internment facility at Camp Bucca, the military said in a brief statement. It provided no other details.

In Baghdad, a parked car bomb struck a convoy of Iraqi police commandos and gunmen opened fire on police on a foot patrol in a mostly Shiite neighborhood in Baghdad on Saturday, police said. The attacks came a day after gunmen stormed a senior Iraqi police officer's home northeast of the capital.

Diplomatic tensions also rose, with the Iraqi Foreign Ministry summoning the Turkish charge d'affaires and calling for an immediate halt of cross-border shelling into northern Iraq, saying such actions "undermine confidence between the two nations and negatively affect their friendship." The statement was the first government confirmation of the shelling.
