KARACHI: The Pakistan Stock Exchange (PSX) came under attack on Monday morning when four heavily armed assailants lobbed grenades at its entrance and opened fire on security guards and officials before being killed in an exchange of fire that also claimed the lives of a police officer and three guards.
Guards fought back, killing all four attackers, the authorities say, but police officers and security personnel are feared to be among the casualties.
The Baluchistan Liberation Army has claimed responsibility for the attack in social media posts.
The BLA have targeted infrastructure projects and Chinese workers in Pakistan multiple times in recent years, including an attack on Beijing's consulate in Karachi that killed four people in 2018.
The militant group has been attacking businesses seen close to China since the North Asian nation started building a road connecting Gwadar port in Balochistan, and crossing deserts and snow-capped mountains, to China's Xinjiang province.
