Malaysia's Islamic party PAS has condemned yesterday's carnage in London - the worst terror attack ever in Britain.

Party secretary-general Kamarudin Jaffar said that the opposition party was "deeply shocked and saddened" by the bombings.

"We believe that this act of violence and the indiscriminate killings of innocent people are in complete contradiction to the teachings of Islam. We therefore unreservedly condemn this action," he said in a letter to British Prime Minister Tony Blair.

At least four explosions rocked the British capital during yesterday's morning rush hour, blowing up a double-decker bus and three underground train stations, killing at least 37 people and injuring more than 700.

British Foreign Secretary Jack Straw said the attacks were likely to be the work of Osama bin Laden's al-Qaeda network.

Kamarudin also conveyed the party's "deep sympathy to the victims, their relatives and the entire population of London" for the tragedy.

Suicide bomber

Meanwhile, AFP reported that Blair had vowed to track down the perpetrators of the bombings.

Three explosions tore apart packed underground trains and one peeled the top off a number 30 double decker bus in 56 minutes of mayhem, beginning at 8:51 am (4.51pm Malaysian time) with a blast between Liverpool Street and Aldgate underground stations.

Although anti-terrorist investigators said it was too early to speculate, several British newspapers were convinced that the attack on the bus had been the work of a suicide bomber.

Blood-spattered and crying, thousands of survivors of the four attacks staggered into the streets.

The entire underground rail network was shut down and terror replaced the euphoria of a day earlier when London was named the host of the 2012 Olympic Games.

The synchronised blasts, detonated without warning, occurred within minutes of each other, in an eerie echo of last year's Madrid train bombings which killed 191 people.

Message for G-8 leaders

The attacks were timed with the opening of the G-8 Summit, where leaders of the world's richest countries are meeting in Scotland to discuss problems of poverty in Africa, climate change and the environment.

PAS' Kamarudin, in his statement today, has a message for the global leaders.

He called on them to continue efforts to seek solutions to the outstanding major global economic and political issues which also constitute the root causes of terrorism.

Earlier today Prime Minister Abdullah Ahmad Badawi also condemned the bomb attacks in London.

Abdullah, who is also the chair of the 57-nation Organisation of the Islamic Conference, urged member countries to uphold the principle of rejecting violence and called on them to be vigilant.
