Two militants attacked the camp number 2, located at the ASF academy in Bitai Abad, near the Jinnah International Airport which had been cleared of militants after fierce clashes between forces and terrorists yesterday.
The attackers failed to penetrate the security cordon and managed to flee into nearby congested residential areas.
ASF spokesman Col Tahir Ali said the incident had been played up and dismissed reports about five terrorists entering the base camp and engaging the security forces.
He said the situation was now under control and the paramilitary Rangers and police had launched a search operation in the vicinity to find the two terrorists.
"The Pakistan army is also carrying out surveillance from helicopters and the situation is under control. The Jinnah international airport is in control of the authorities," he said.
A spokesman for the Pakistan International Airlines said flight schedule had been disrupted as passengers and visitors to the Jinnah airport were evacuated to safe locations after the attack at the ASF camp this morning.
"Some flights were disturbed and a foreign airline flight to Dubai couldn't take off on time due to the disturbance but now the airport and runaway is under total control of security forces and operations are getting back to normal," he said.
The Twitter account of the CAA, @AirportPakistan tweeted that EK 606 from Dubai which was expected to arrive at Karachi airport at 12:50pm is now returning to Dubai.
This is the same area from where a group of 10 terrorists, who attacked and laid siege to the old Karachi airport on Sunday night, gained access to the restricted site.
Eleven airport security guards, along with a paramilitary ranger and a policeman, 14 civilian workers and 10 militants were killed in the previous attack.
