The victims were walking Saturday on the border of the Gravesend and Midwood neighborhoods when two cars collided and one veered into their path, the police said.

A mother and her two young daughters were struck by a driver and killed in Brooklyn on Saturday, and a third child is in critical condition.

At least nine people were rushed to the hospital Saturday afternoon following a crash on a busy stretch of Brooklyn road during the hottest day of the year so far. FDNY officials said four people were transported from the crash site in Midwood with critical injuries.
