In a move sought by India and the U.S., the panel said the charity Jamaat-ud-Dawa was a front for the Pakistani militant group Lashkar-e-Taiba and subject to U.N. sanctions on terrorist organizations. It also designated four suspected plotters of the Mumbai attack as terrorists subject to sanctions. They include Zaki-ur-Rehman Lakhvi, Lashkar's operations chief, whose arrest was announced Wednesday. The others are Muhammad Saeed, the group's leader; Haji Muhammad Ashraf, its chief of finance; and Mahmoud Mohammad Ahmed Bahaziq, a financier with the group.
