An official in the stock exchange centre said the gumen opened fire at the entrance and have now entered the stock exchange’s grounds.
Police says, the attackers in Pakistan stormed the stock exchange building of the country’s financial hub Karachi, with at least four people killed.
Heavily armed special forces surrounded the building of the Pakistan State Bank, and several national and international financial institutions.
There was no instant facts known on how many gunmen are involved and whether they have been able to enter the building itself in Monday’s attack.
According to a broker inside the stock exchange, Yaqub Memon said he and colleagues are huddled inside their offices.
Local TV stations are showing police surrounding the building but still lingering outside the high walled compound of the stock exchange.
