The mayor of Newark has imposed a curfew around an immigration detention center in New Jersey after a series of intense clashes between protesters and police.

An unassuming industrial area on the outskirts of Newark, New Jersey, is a hub of discourse this week as one day after another, protesters clash with federal agents outside an ICE detention facility while lawmakers call for inspections and oversight.

Protesters and New Jersey State Police clashed again Sunday night near Delaney Hall, despite a 9 p.m. curfew imposed by Newark Mayor Ras Baraka.

Protesters clashed with the New Jersey State Police outside a federal immigration detention center again Saturday night, pushing against barriers and shouting at troopers, who sprayed gas while responding in riot gear.

Newark, N.J., Mayor Ras J. Baraka instituted a curfew early Sunday in the area around an immigration detention facility.

Advocates outside protested conditions. Detainees inside have staged a hunger strike. And federal officials called in New Jersey police at the gates.
