Four people were killed and seven injured today after a bomb exploded on a train in eastern Turkey, military officials said.
The four dead and three of those injured were soldiers travelling on the train in Bingol province between the eastern towns of Elazig and Tatvan when the blast occurred around 10am.
It was not clear who planted the explosives but Kurdish separatist rebels, far-leftist militants and Islamist radicals have all staged bomb attacks in Turkey in the past.
