Ten people were injured, including six children, in a crash Saturday in Woodland Hills, the Los Angeles Fire Department said.

The crash on the eastbound 101 freeway at Valley Circle Boulevard happened just after 1 p.m.

With all but one eastbound lane still closed an hour later, traffic was paralyzed for miles. Most cars exited on Calabasas Road, which also was backed up, said Leland Tang, a California Highway Patrol officer who was caught in the traffic himself.

Brian Humphrey, a Fire Department spokesman, said two of the injured children were ejected from a vehicle or vehicles.

Their conditions weren't available, but Tang said it did not appear anyone had been killed. The cause of the accident was still being investigated.
