Improvised pipe bomb at Colombo airport diffused by Sri Lanka Air Force

New Delhi : An improvised pipe bomb was discovered at the Sri Lanka's Colombo airport; it has been successfully diffused by the Sri Lankan Air Force, said police.

The police sources told a news agency AFP that a "homemade" pipe bomb had been found late Sunday on a road leading towards the main terminal, which remains open with heavy security after Easter Sunday's deadly bomb attacks.

"It was a homemade bomb, with explosives put into a pipe," said the source.

The discovery of the pipe bomb comes a day after a series of bomb blasts rattled a couple of churches and hotels in and around Colombo, leading to a death of over 290 people, including 27 tourists.

"It was a crude six-foot pipe bomb that was found by the roadside," an air force spokesman said. "We have removed it and safely defused it at an air force location."

Due to strict checking, there is a slight delay and disruption in the airport services. The passengers have been asked to report to the airport at least four hours before the time of departure.

The apparently coordinated attacks were the deadliest to hit the country in the decade since the end of a bloody civil war that killed up to 100,000 people and evoked painful memories for many Sri Lankans.
