Decision will be challenged in high courtISLAMABAD - A Pakistani court acquitted on Saturday three men accused of involvement in a 2008 suicide car-bomb attack on the Danish embassy in Islamabad, a public prosecutor said. The court acquitted the trio on the basis of “insufficient” evidence against them, said the prosecutor, Mohammad Tayyab. “We produced 32 witnesses before the court. Two of those saw (the trio) them on the spot signalling attackers to go ahead and later identified them in a police station,” said Tayyab. “But still the judge found insufficient evidence.” The men were arrested several months after the attack that killed six people. An Al-Qaeda leader said one of the bombers had come from Saudi Arabia. Tayyab said he would challenge the acquittal in the high court. “We believe our case is very strong and the high court will analyse our evidence again and decide the case in our favour,” he said. Suspects in terrorism-related cases are often acquitted due to what critics say is law enforcement agencies' inefficiency and outdated investigative methods. Pakistan has been fighting Al-Qaeda- and Taliban- linked militants who have killed thousands of people in suicide and bomb attacks since Islamabad joined the US-led war on terror after the Sept 11, 2001, attacks on the United States.
