Islamabad  - Police foiled bombing plans by seizing six terrorists, including three would-be suicide bombers, and a large quantity of explosives laden in three vehicles in the garrison city of Rawalpindi, officials said on Friday.

Rehman Malik, Security Advisor to prime minister, said the arrests were made on Thursday night in one of the densely populated areas of the city about 30 kilometres from Islamabad.

He refused to provide further details, saying these were "too sensitive" to be shared.

However, the local police officers said around 1,100 kilograms of explosive material from the three cars.

A police officer who spoke on condition of anonymity said the first vehicle was stopped during a routine patrol in Dhook Kala Khan area Thursday night and around 500 kilogram of explosives was recovered.

Two other vehicles were seized later in the same area with about 600 kilograms of explosives, detonators and automatic rifles.

The official claimed the initial investigation showed the terrorists were planning to strike President Musharraf's residence in Rawlapindi in three simultaneous bombings.

But the city police chief Rao Mohammed Iqbal refused to confirm that claim. "We are interrogating a number of persons apprehended during the action and when solid information comes out we will share with the media," he said.

The seizure came five days after a single suicide bomber blew up his explosive-laden car next to the main entrance of the Danish embassy in the nearby capital city of Islamabad, leaving six people, including a Danish citizen of Pakistani origin and two Pakistani employees of the embassy. (dpa)
