At least 70 Kenyan students were massacred Thursday when Somalia's Shebab Islamist group attacked a university, the interior minister said, deadliest attack since US embassy bombings in 1998.
"We are mopping up the area," Interior Minster Joseph Nkaiserry told reporters, saying that four gunmen had been killed after Kenyan troops launched an assault on the final building where the insurgents had holed out for over 12 hours.
