A roadside bomb exploded in southeast Turkey on Saturday moments after the convoy of local governor passed, in what appeared to be an attack by Kurdish rebels, an official said. Gov. Kadir Kocdemir was on his way to a meeting organized to protest increased terror attacks in the region, the official said on condition of anonymity. Turkish civil servants are rarely permitted to speak on the record. No injuries were reported, but some of the cars in the convoy were slightly damaged, he said. The blast was triggered by remote control, some 18 miles from the town of Alacakaya in Elazig province, the official said.Meanwhile, police in the southern city of Mersin said a car explosion Friday appears to have been a bomb that exploded prematurely in the lap of the would-be bomber. The bomb killed the man and injured the driver, said Suleyman Ekizer, Mersin's deputy police chief. Mersin's governor, Atilla Osmancelebioglu, suggested that the two men may have been on their way to carry out an attack when it exploded. He did not say if the two were suspected Kurdish rebels.
