A New Jersey mayor says his city has been “unlawfully terrorized” after federal agents detained multiple people Thursday during what Immigration and Customs Enforcement called “a targeted enforcement operation.

The Immigration and Customs Enforcement agency confirmed the “targeted enforcement operation” at a worksite in Newark, which is a sanctuary city.

Mayor Ras Baraka said he was "appalled" and "angry" and blasted ICE for also detaining U.S. citizens, including a veteran. ICE said citizens may be questioned during an investigation.

Newark Mayor Ras Baraka, members of the city council, and state and federal representatives are expected to hold a news conference Friday morning about what the mayor is calling a “raid” by Immigration and Customs Enforcement officers at a business there on Thursday.

Mayor Ras Baraka said the state's largest city will not stand idly by while people are “unlawfully terrorized,” announcing plans to hold an event to address the situation.

New Jersey officials are raising questions after U.S. Immigration and Customs Enforcement officers raided a Newark business on Thursday just days into President Donald Trump's second administration.

An operation carried out by Immigration and Customs Enforcement (ICE) agents has sparked concern and heightened anxiety among some communities in Newark, as outraged local officials have pledged to investigate the event and to protect those who they believe should be shielded under the law.

Immigration and Customs Enforcement agents appear to have stepped up their detention of unauthorized immigrants, taking more than 500 people into custody on Thursday, almost twice the average number of daily arrests late last year.

President Donald Trump is planning to travel to California to survey the wildfire damage in his first presidential visit since his inauguration.
