At least seven people have been killed after gunmen stormed the Pakistan Stock Exchange in the southern city of Karachi, firing indiscriminately as they entered the building complex, rescue officials say.
Four attackers stormed the building on Monday morning as trading began at 10:00am local time (05:00 GMT), carrying hand grenades and firing automatic rifles.
All four attackers had been killed by police and security forces responding to the attack, said Faisal Edhi, chief of the Edhi charity and ambulance service which serves the city.
“The attackers had hand grenades with them. Two of them were killed at the gate and two were killed further inside the building complex,” said Edhi, whose office is located opposite the targeted building in Karachi’s main commercial district.
“We were hearing explosions going off [from our building],” he said.
The dead include the four attackers, a policeman and two civilians, said Edhi. Seven others had also been wounded in the attack, he said.
The Baloch Liberation Army armed group claimed responsibility for the attack, in a statement released while the security operation to clear the building was ongoing.
“Majeed brigade of Baloch Liberation Army today has carried out a self-sacrificing attack on Karachi stock exchange,” read the statement, emailed to Al Jazeera.
‘We are all terrified’
Witnesses who were working inside the building at the time of the attack described hearing heavy gunfire and explosions as the attackers entered the complex.
“We are all terrified,” said Abid Habib, director of the Pakistan Stock Exchange (PSX). “There was gunfire and everything, and suddenly everyone was rushing to the windows to see what is happening.
“Because the firing was close by, everyone was very worried and we closed our outside doors.”
Security forces responded to the attack, and paramilitary Rangers were clearing the building, Habib said.
Video footage of the attack – shot by an office worker in a building opposite the PSX complex and obtained by Al Jazeera – showed four attackers dismount from a car and take up positions at a security barrier to the building, firing at security guards.
Trails of blood were splattered across the stairs and an adjoining corridor of the building, two other videos and images sent by workers inside the building showed.
The PSX is Pakistan’s main stock exchange, with more than 2,000 employees normally working in the building for the exchange and associated trading companies.
Employee turnout was lower on Monday due to the coronavirus pandemic, when many companies opting to allow their workers to work from home, said Habib.
Trading on the PSX continued uninterrupted throughout the attack on Monday, traders and equity analysts told Al Jazeera, as the stock exchange operates through an electronic online system.
