Six killed in Kyiv shooting

The head of Ukraine's patrol police, Yevhen Zhukov, resigned after two officers were seen on video fleeing the scene during the initial gunfire.

The suspect reportedly sought to carry out an attack similar to the Columbine school shooting.

Ukrainian prosecutors have opened an inquiry into potential police negligence during the 40-minute standoff.

Mayor Vitali Klitschko confirmed that one child is among those still receiving treatment for gunshot wounds.
