U.S. President Donald Trump has intensified his hardline immigration policy by calling for a broad expansion of arrests and deportations carried out by Immigration and Customs Enforcement (ICE) agents.

In a post on his Truth Social platform late Sunday, the Republican president called on ICE and other agencies to "do all in their power" to carry out what he described as "the single largest Mass Deportation Program in History."

Trump specifically targeted Democrat-led cities, including Los Angeles, Chicago and New York, urging the federal agents to step up enforcement efforts.

The president's hardline approach has sparked widespread protests across several U.S. cities.

Demonstrations in the U.S. intensified recently after Trump deployed National Guard troops and marines to Los Angeles, a move strongly opposed by California Gov. Gavin Newsom, a prominent Democrat and potential 2028 presidential contender.
