The FBI announced on June 8, 2005 the arrest over the weekend of Hayat and his Pakistani-American son living in California after the son admitted to attending an al Qaeda training camp in Pakistan. Hamid Hayat, 23, and his father, Umer, 45, of Lodi, 35 miles (60 km) to the south of state capital Sacramento are being held in Sacramento on charges of lying to federal authorities. According to an FBI affidavit, Hamid Hayat told agents he attended an al Qaeda training camp in Pakistan for about six months in 2003 and 2004. "Hamid further stated that he and others at the camp were being trained on how to kill Americans," the affidavit said. REUTERS/Handout/File HK/GN/pn
