Mohammad Azeem, an official at the charity Eddie Rescue Center, said police and security officials have confirmed death.
Rescue and paramilitary security personnel are on the scene, Azeem said.
According to CNN’s affiliate Geographic News, the video shows security and roadblocks outside the Karachi Stock Exchange.
Abid Ali, director of the Pakistan Stock Exchange, said in an Earth News briefing that four attackers entered the compound and started shooting, but were killed by security forces.
Ali said: “Four attackers came in from the parking lot. They threw a grenade at the main entrance of the KSE (stock exchange) and then opened fire at will.”
“The attacker was wearing a uniform that looked like a police uniform. All four people were killed and the situation is currently under control.”
The General Director of Pakistan Rangers Sind (Pakistan Rangers Sind Province), General Oma Ahmed Buhari (under claimed) claimed that the Balochistan Liberation Army organization was responsible for the attack.
Buhari said: “We are investigating further to find out who these people are.”
A BLA source confirmed this statement. He said: “Today, the Majeed Brigade of the People’s Liberation Army of Bal Road Branch carried out a self-sacrifice attack on the Karachi Stock Exchange. Our combatants were inside the building and took control of the area. .”
The BLA has carried out low-level separatist rebellions against Pakistan’s targets for nearly two decades. The organization was originally established because of anger over the state’s monopoly on mineral resources in Balochistan.
It previously killed and kidnapped Chinese engineers working in the province.
The tweet wrote: “Once the situation is under control and we know more details, we will issue a more detailed statement in due course. At present, the shooting has stopped and reinforcement work is in place.”
The Pakistani stock exchange administration issued a message saying that “commando” had entered the compound and “four terrorists” had died.
The government told the workers in the building to stay on the higher floors. “The rangers will sort out the compound and let everyone leave in an orderly manner.”
Karachi’s Pakistan Stock Exchange is the largest in the country. It is located in the city’s financial center, where all major banking and financial services are located, and usually has a large number of security departments.
