Earlier in the day Pakistan police arrested a suicide bomber and claimed to have foiled a terrorist attack being planned on the Kamra airbase in Punjab province.

Counter Terrorism Department SSP Junaid Shaikh told the media in Karachi that they had arrested a high-profile militant of the largely unknown Tehreek-e-Imarat Islamia Afghanistan.

"Umar Hayat alias Darvesh was planning to carry out a terrorist attack on the Kamra airbase in Punjab and we have recovered suicide jackets, jihadi material, CDs and maps from his possession," Shaikh said.

"We arrested Umar who is a suicide bomber from a safe house in MPR colony in the Orangi town after conducting a raid on an intelligence tip-off," he added. "We got a tip-off that a high profile militant from Afghanistan was hiding out in Orangi," he stated.

The SSP said the held suspect has allegedly trained two suicide bombers identified as Raz Mohammed and Taj Mohammed. "The purported suicide bombers had been sent to Punjab to carry out a terror act at the Kamra airbase but they couldn't do it due to extensive security arrangements and had to return to Karachi," Shaikh said.

The suspect, he added, was also planning to carry out terror attacks on Eidgahs in Karachi during Eidul Azha, in addition to planning attacks on military installations in the metropolis.
