KARACHI - The second attack on Pakistan's Karachi airport in as many days ended on Tuesday without casualties, officials said, but with the escape of the two gunmen involved.
"It was not such a big attack, two people came towards the ASF (Airport Security Force) checkpost and started firing," Colonel Tahir Ali, a spokesman for the force told reporters. "Nobody has been killed or injured," he added.
Army spokesman Major General Asim Bajwa confirmed the incident was over, but said three to four assailants were involved.
"3-4 terrorists fired near ASF camp, ran away. No breach of fence, no entry. Chase is on, situation under control," he tweeted.
The attack occurred at around 12.30pm (0730 GMT) at a checkpost guarding the entry to an ASF camp 500 metres (yards) from the airport's main premises, and around a kilometre from the passenger terminal.
Ali said the attackers "ran away after shooting and because we are on high alert, under the standard operating procedure we called in (paramilitary) rangers and the army".
He added that ASF personnel had fired in the air but had not exchanged gunfire with the militants.
