A search continued Tuesday for a pair of gunmen who opened fire on a man in a New York City playground injuring two children, ages 9 and 11, caught in the crossfire.

The young victims are among 324 children 11 years old or younger who have been shot in incidents across the nation in the first five months of the year, including 94 who were killed, according to the Gun Violence Archive, a website that tracks all U.S. shootings
