SANAA (AFP) - A court in Yemen, under mounting US pressure to fight Al-Qaeda after a foiled air cargo bomb plot, ordered Saturday the arrest by any means of a US-born cleric for alleged links to the terror group. Judge Mohsen Alwan called on prosecutors to forcibly arrest Anwar al-Awlaqi and a relative, Othman al-Awlaqi, whom a Sanaa court has charged with incitement to kill foreigners and members of security services. Public prosecutor Ali al-Samet told the court the pair had failed to appear for a second time on Saturday before the court that specialises in terrorism cases. The charges against them arose during the trial of Yemeni Hisham Mohammed Assem, who was in court to face charges of killing French energy contractor Jacques Spagnolo near the capital Sanaa last month. All three men are accused of forming an armed gang to carry out criminal acts and to target foreigners and security forces on behalf of Al-Qaeda. The prosecution had told the court at Tuesdays first hearing that the Yemeni-American cleric Awlaqi had corresponded with Assem for months, encouraging him to kill foreigners. Assem, who had said he was tortured, denied the charges on Saturday, saying he killed the French contractor over a personal feud and not due to incitement by Awlaqi. The judge also ordered the public prosecutor to provide Anwar and Othman al-Awlaqi with a lawyer. The trial was adjourned until next Tuesday. The parcels containing the powerful explosive PETN hidden in ink toner cartridges were found to have been sent by air freight from Sanaa on commercial airlines. Washington believes the parcel bombs, uncovered on Thursday in Britain and Dubai en route to the United States, were the work of Saudi militant Ibrahim Hassan al-Asiri, a suspected Al-Qaeda bombmaker. Awlaqi has not immediately been linked to the parcel bombs, but US officials have long accused him of instigating terrorism from Yemen, where he is believed to be hiding in a remote area of Shabwa.
