Ankara bombing: Investigation into Turkey’s deadliest terrorist attack to be ‘completely focused’ on Isis

The West’s key frontline ally in the battle against Isis has been plunged into a state of turmoil, engulfed by violence and recrimination after the most deadly terrorist attack in Turkey’s history.

Amid fears that the war in Syria and Iraq has crossed the border on to Turkish soil, the death toll from the blasts at a Kurdish peace march increased from 95 to 128, according to the pro-Kurdish HD party. Security sources said the investigation into the bombings would be “completely focused” on Isis. The attacks bore striking similarities to a suicide attack in Suruc in July this year that killed 33 pro-Kurdish activists.
