MOSCOW • Relatives wept and hugged as the nine people killed in a school shooting in the Russian city of Kazan were buried Wednesday, which was declared a day of mourning in the predominantly Muslim republic of Tatarstan.

A huge pile of flowers grew at a makeshift memorial outside School No. 175 in the city 430 miles east of Moscow where the gunman opened fire on Tuesday, sending students diving under their desks, running from the building or even jumping from windows on upper floors.

He also detonated a homemade bomb.
