NEW HAVEN, Conn. (AP) — Two men extradited from Britain pleaded not guilty Saturday in a Connecticut court to federal charges that they provided terrorists in Afghanistan and Chechnya with cash, recruits and equipment.

Babar Ahmad, 38, and Syed Talha Ahsan, 33, were arraigned amid heavy security in U.S. District Court in New Haven hours after arriving in the U.S. after yearslong extradition fights in England. They were kept detained while they await trial in Connecticut.
