A suicide bomb explosion in southwestern Pakistan killed at least three paramilitary personnel and wounded 15 others.
There are conflicting reports of how the attack took place. Some reports said the attacker walked through a manned check post 25km south of Quetta of Balochistan province and detonated himself. Other reports claimed the suicide bomber on a motorcycle packed with 6kg explosives rammed into one of the vehicles part of a convoy.
Armed group Pakistan Taliban, known by the acronym TTP, claimed responsibility for the attack.
It was the first time TTP claimed an attack on Pakistani security forces since the Taliban took control of neighboring Afghanistan.
TTP, which renewed its allegiance to the Afghan Taliban after the fall of Kabul, has recently stepped up its campaign against the Pakistani army.
“Condemn the TTP suicide attack on FC checkpost in Mastung Road, Quetta,” Prime Minister Imran Khan said in a tweet.
The province of Balochistan has seen an uprising by Baloch separatist groups for nearly 20 years, calling for independence for the gas and mineral-rich province. Most attacks on security forces in Balochistan in the recent past have been claimed by Baloch separatist groups Balochistan Liberation Army and Balochistan Liberation Front.
Balochistan, bordering Iran and Afghanistan, is a key province in southwest Pakistan, where China has been working on projects related to the China-Pakistan Economic Corridor. The projects, including road construction, power plants and agricultural development, have cost billions of dollars.
China has in recent years also played a key role in developing the deep-water port of Gwadar on the Arabian Sea. But there have been attacks on Pakistanis and Chinese working on the economic corridor projects.
