Gunmen attacked Jinna International Airport, on the southeastern coast of Pakistan in Karachi, on Sunday, June 8.
At least four airport security workers were killed, and there are reports that some of the gunmen were also either killed or injured.
Social media reports described at least one airplane blown up with grenades by the gunmen.
All roads leading to Jinna Airport were closed and all flights in and out of the airport are suspended, and flights were being diverted elsewhere, according to the BBC.
As of the time of publication, there were no indications of who was responsible for the attack. Smoke was reported billowing from the old terminal at the Karachi airport.
There are unconfirmed reports that at least one airplane has been hijacked by the terrorists.
UPDATE: As of 10:00 p.m. east coast time, the attack was over. Thirteen Pakistanis were killed, including members of the security, aviation and the state airline, and one civilian. All ten of the gunmen are dead. The gunmen stormed the airport wearing police gear and suicide vests.
Several Twitter accounts run by the Pakistani wing of the Taliban, Tehrik-i-Taliban Pakistan (TTP) claimed responsibility for the Karachi attack, the IBTimes reported. However, there were also reports that at least some of the weapons found on the dead terrorists were from India.
There were several other violent clashes earlier in the day, although the connections, if any, between those incidents and the airport attack is still unclear.
