A Muslim advocacy group is announcing a reward for information leading to the arrest of the gunman who killed a New York City mosque leader and his associate.

Police say 55-year-old Imam Maulama Akonjee and 64-year-old Thara Uddinwere were shot near the Al-Furqan Jame Masjid mosque in Queens as they left afternoon prayers on Saturday.

The Council on American-Islamic Relations will announce on Monday a $10,000 reward for information leading to the arrest and conviction of the shooter.

Police say they have not yet determined a motive for the killings, but some in the Bangladeshi Muslim community served by the mosque worry it could be a hate crime.

Muslim community members will gather in Brooklyn on Monday to hold Islamic funeral prayers for the two men.
