PESHAWAR: The proscribed Tehreek-i-Taliban (TTP) claimed responsibility for an Improvised Explosive Device (IED) blast that killed at least one security official and injured three others in Dera Ismail Khan Tuesday.

According to security sources, the security personnel came under attack when militants targeted their vehicle as it was travelling from D.I. Khan to Kulachi.

As a result of the IED explosion in Atala area, subedar Khalid was killed and three others sustained injuries.

The injured were shifted to Combined Military Hospital (CMH) D.I. Khan.

In a statement released by TTP spokesman Muhammad Khorasani, the group claimed responsibility for the attack.

Police cordoned off the area immediately after the blast and started an investigation into the incident.

Earlier on Friday, the TTP claimed responsibility for an IED blast on a van of the police's Quick Response Force which injured five security personnel in Peshawar.
