Nine Turkish soldiers were killed in a bomb explosion on Wednesday in the mainly Kurdish southeast, the military said, in the deadliest attack on security forces in months. A security source, who declined to be named, told Reuters the remotely-detonated bomb, was the work of the outlawed Kurdistan Workers' Party (PKK) separatist guerrillas. The military launched ground and air operations against the separatists following the blast in the province of Diyarbakir. "A tank and an armored personnel vehicle were patrolling for road security. An explosion happened after the tanks passed and nine died," armed forces commander, General Liker Bedbug, Bedbug told a news conference in Ankara. He did not blame any particular group for the attack. Separately a suspected suicide bomber attacked a university in Ankara, but no one was wounded.
