Criticism mounted Saturday over a wall U.S. troops are building around a Sunni enclave surrounded by Shiite areas in Baghdad, with residents calling it "collective punishment" and the local council leader saying the community did not approve the project before construction began.

Violence continued Saturday, with at least three people killed when a bomb left on a bus exploded in Baghdad's Sadr City neighborhood, police said. The minibus was gutted by flames and its windows shattered.

Gunmen stormed a house in Kirkuk, 180 miles (290 kilometers) north of Baghdad, killing a mother, father and their two teenage daughters, police said. The victims were Kurds who had received death threats from al Qaeda-linked militants operating in the area, witnesses said.

A U.S. soldier was also killed Saturday by a roadside bomb southwest of the capital, the military said.
