Tehreek-e-Taliban Pakistan (TTP) in a statement said it had “nothing to do with the attack” in the northwest of the country, which also wounded three other officers.

The convoy of more than 10 foreign ambassadors was passing through the picturesque town of Malam Jabba in the Swat district when it was hit by a roadside bomb.

Top diplomats from Russia, Bosnia and Herzegovina, Portugal, Kazakhstan, Tajikistan, Turkmenistan, Iran, Ethiopia, Rwanda, Zimbabwe, Indonesia, and Vietnam were part of the convoy.

In a statement, the Russian embassy said its ambassador was taking part in the trip along with several other ambassadors.

The foreigners were unhurt in the incident and later returned to Islamabad, Pakistan’s foreign office said on Sunday.

Police officials said the trip was organised by Islamabad and Swat’s Chamber of Commerce to promote the region’s local industries, including handicrafts and gemstones.

Swat – a snow-capped mountain valley split by turquoise waters – is one of Pakistan’s most famed beauty spots, but its reputation has a dark side.

In 2012, Malala Yousafzai was shot in the head by the TTP while campaigning as a schoolgirl for education, activism that later earned her the Nobel Peace Prize.

The Pakistani Taliban historically has roots in Afghanistan and shares the same ideology as the Afghan Taliban.

From 2007 to 2009, they killed thousands of civilians and seized control of several districts before being driven back by the military.

Pakistan has witnessed a dramatic uptick in attacks since the Taliban seized control of Kabul in 2021, but diplomats are rarely targeted.

Islamabad says such offensives are being launched from neighbouring Afghanistan by various militant groups, many linked to the TTP, which the Taliban authorities deny.
