Note: The counter-protesters are said to be pro-Israel but no one really knows who they are:

Dozens of police are marching out of the Murphy Hall parking lot toward Dickson Plaza, the site of the encampment and ongoing protests. The majority of them appear to be affiliated with California Highway Patrol.

"USA, USA!" shout a large swath of counter-protesters as they follow police to the encampment site. "Get those pieces of s" out of the f" grass!" one says.

At the request of UCLA, due to multiple acts of violence within the large encampment on their campus, the LAPD is responding to assist UCLA PD, and other law enforcement agencies, to restore order and maintain public safety.

Statement from Councilwoman Katy Yaroslavsky: "Everyone has a right to free speech and protest, but the situation on UCLA's campus is out of control and is no longer safe. I'm grateful to LAPD and Mayor Bass for stepping in to ensure the safety of everyone on campus."

Live updates from NBC News:

Police separate rival groups at UCLA but protesters refuse to leave

Rival groups that had earlier been involved in violent confrontations appeared to have been separated by a line of police officers by 2 a.m. (5 a.m. ET).

The scene is less chaotic than earlier, but a vocal group of protesters still refuses to leave despite police calls for them to go home.

Footage broadcast by the Reuters news agency showed a police officer saying through a loudspeaker "the encampment is over for tonight," urging people to leave.

But the pro-Palestinian group chanted in response: "We're not leaving, you don't scare us."
