A suicide car bombing at a checkpoint in Pakistan’s capital, Islamabad, has killed at least one police officer and wounded several other people, according to officials.

The Tehreek-e-Taliban Pakistan (TTP) armed group, also known as the Pakistani Taliban, claimed responsibility for Friday’s attack in a text message sent to a Reuters news agency reporter.

The bombing took place near the police headquarters on a main road that leads to government buildings housing the country’s parliament and high offices.

The car that was used in the attack was packed with explosives and headed for a high-value target in Islamabad, the interior ministry said in a statement, without giving any other details.

Interior Minister Rana Sanaullah told Geo News TV that had “the car reached its target, it would have caused heavy losses”.

The capital was on high alert due to threats of such an attack, and a big tragedy was averted with timely intervention, the minister said.

The TTP has been fighting Pakistan’s government since 2007 and has carried out dozens of attacks aimed at civilians and security forces across the country.
