Militants have stormed a military post in northwestern Pakistan, killing at least 23 people in a gun and suicide bomb attack, according to the Pakistani military.

Iran PressAsia: A suicide bomber detonated his explosive-laden vehicle at a police station gate in northwest Pakistan early Tuesday, killing at least 23 officers, wounding 32 others and causing part of the building to collapse, the military and officials said.

A man detonated a truck filled with explosives at the main gate of the police station in Dera Ismail Khan, before other militants armed with guns attacked the police station, a local police officer told the Associated Press.

All six assailants were killed in the shoot-out, the Pakistani military said.

“The attempt to enter the post was effectively thwarted, which forced the terrorists to ram an explosive-laden vehicle into the post, followed by a suicide bombing attack,” said the military.

“The resulting blasts led to the collapse of the building, causing multiple casualties.”

The militant group Tehreek-e-Jihad Pakistan (TJP) claimed responsibility for the attack and said its fighters had killed 20 police officers. 219
