The four assailants, who arrived in a silver Corolla car, attempted to storm the headquarters of Pakistan’s largest stock exchange on Monday, using grenade and guns in the attack.
The attackers, who were dressed in police uniforms, initially threw a grenade before opening fire on a security post outside the building, killing two guards and a police officer. Seven others sustained injuries.
Security forces, however, intervened and foiled the attack, according to media reports. Karachi police chief Ghulam Nabi Memon told Reuters that all the four gunmen were killed in the assault.
The Pakistani Stock Exchange said on Twitter, “The situation is still unfolding and management, with the help of security forces, is managing the security and controlling the situation.”
“We will issue a more detailed statement in due course once the situation is under control and more details are known. For now, firing has stopped and reinforcement are in place,” the tweet read.
The Pakistan Stock Exchange is located in Karachi’s financial hub, where all major banks and financial services are located, and where security is usually tight.
The separatist Baloch Liberation Army from Balochistan claimed responsibility in a Twitter post, but Reuters said the group’s spokesman was not available for comment.
Thousands of Pakistanis have lost their lives in bombings and other militant attacks since 2001, when Islamabad entered into an alliance with the US in Washington’s so-called war on terror.
The Pakistani army has launched frequent counter-militancy offensives over the past years, but sporadic acts of terror by militants continue to target security forces as well as civilians.
