KARACHI, Feb 18: Police said they found on Monday four live rockets planted on a wooden frame with timing devices and aimed at the airport.

A police spokesman said that during investigation into an explosion caused by a rocket at a Shah Faisal Colony house on Saturday night, information about the four rockets lying in an open plot in the proximity of the airport was received.

The police rushed to the spot with the ASFs Bomb Disposal Squad and defused the 197mm rockets. An improvised timing device was connected to each of the rockets, he said. The police had started questioning of the people living in the adjoining localities for a clue to suspects.

The police sources said that one of the five rockets had been launched on Saturday night that had hit the house of Imtiaz in Shah Faisal Colony and left one man injured and the house and some vehicles damaged.

They said that the rest of the rockets could not be launched as their detonator did not work due to low battery.
