ISLAMABAD, July 26 (Xinhua) -- An Uzbek national arrested in Pakistan has told interrogators that al-Qaida organized this year's deadly suicide attack on the United States consulate in Pakistan's southwest port city Karachi, a security official said Wednesday.

    Five people including an American diplomat were killed in the suicide bombing outside the U.S. mission on March 2, the eve of a visit by U.S. President George W. Bush to Islamabad.

    The website of local newspaper The News quoted the security official as saying that the Uzbek al-Qaida suspect was picked up a few weeks ago in Wana, the main town in the restive South Waziristan tribal region bordering Afghanistan.

    The suspect has revealed that the attack was planned by an al-Qaida unit and executed by local militants, the official with anonymity said.

    "He said he brought the plan to Karachi from Wana and handed it over to local militants for execution," the official said.

    "The whole plan to bomb the consulate before President Bush's arrival was conceived by al-Qaida in the tribal territory of Waziristan," he said.

    "We are very close to resolving the case and we believe that most of those who planned the attack were Uzbeks." Karachi police chief Niaz Siddiqui said investigations into the attack now showedal-Qaida was responsible. Enditem
