A Florida federal judge has dismissed terrorism support and conspiracy charges against a Muslim cleric accused along with his father of funneling cash to the Pakistani Taliban.

U.S. District Judge Robert Scola ruled Thursday there was insufficient evidence against 26-year-old Izhar Khan, imam at a mosque in suburban Margate. Scola let stand the case against Khan’s father, 77-year-old Hafiz Khan. Trial is continuing in Miami federal court for the father.

Scola ruled that Izhar Khan’s involvement in two transactions totaling $1,100 did not show he was supporting Taliban fighters. Charges were dropped earlier by prosecutors for another of Hafiz Khan’s sons.

Hafiz Khan has pleaded innocent to four terrorism support-related charges that each carry maximum 15-year prison sentences.
