PARIS (Agencies) Two suspected Islamist extremists from France have been arrested in Pakistan after meeting with a man accused of ties to al-Qaeda, officials said Thursday. The French men, who have not been identified publicly, were arrested at a bus stop in Lahore in late January after going there from the airport with a man identified as Tahir Shehzad, a Pakistani intelligence official said. Information from Shehzad led Pakistani agents to Umar Patek, an Indonesian al-Qaeda linked suspect detained on January 25, the official said. The French men had intended to travel with Patek to North Waziristan region where al-Qaedas top command is based, he said on condition of anonymity. It was not immediately clear if the men were suspected of plotting a terror attack but Western counterterrorism and spy agencies have been intensely monitoring the movements of suspected militants from their countries to Pakistan out of concern they could train there and return home to carry out attacks. One of the French citizens is of Pakistani origin and the other is a convert to Islam, the Pakistani official said. A French counterterrorism official confirmed the arrests on condition of anonymity because of the sensitivity of the case. Frances main spy agency, DGSE, and the Foreign Ministry declined immediate comment. The French men are still in custody, the Pakistani official said.
