A 7-year-old boy was struck by an MTA bus while holding his mother’s hand in Brooklyn last night, authorities and family members said.

Ridhoy Kahlil was struck by the bus after he and his mother, Nur Uddin, 34, exited their car near their Crescent Street home in East New York at about 6 p.m.

“There was blood on the street and on his face,” said Uddin.

Kahlil was taken to Brookdale Hospital with head injuries that included a broken bone behind his right ear, but he is expected to survive.

Cops said there was no criminality involved in the accident.
