Afghan President Hamid Karzai has expressed support for the Pakistani government's decision to raid a radical mosque in Islamabad on Tuesday.

Mr. Karzai told reporters Wednesday that his nation fully supports Pakistan's campaign against extremists. He also called on Pakistan to take an equally decisive stand against militants who are crossing the border into neighboring Afghanistan and killing Afghan civilians.

Pakistani officials say their government is bracing for a possible militant backlash after Tuesday's raid at the Red Mosque compound.

Officials warn there could be an uprising along the border with Afghanistan, where the mosque's pro-Taleban leaders had many supporters.
