Demonstrators gathered outside Los Angeles City Hall Wednesday as protests against the Trump administration's crackdown on immigration continued in LA for a fourth day.

Draped in Mexican and Salvadoran flags, roughly 1,000 demonstrators gathered near City Hall shortly before noon, blocking traffic at Spring and Temple streets.

The large group, calling for a National Day of Action, could be seen through aerial footage walking in the middle of Spring Street, moving along to block an intersection at Chick Hearn Court and 11th Street all the while waving Mexico flags and carrying protest signs.

The Los Angeles Police Department said a juvenile, male protestor was stabbed and transported to a hospital in critical condition.
