Anyone entering US illegally will be arrested, detained and deported: Trump

Anyone entering the US illegally would be arrested, detained and then deported back, President Donald Trump has warned as he threatened three Central American nations to halt a migrant caravan from heading to America or lose millions of dollars in foreign aid.

Trump's warning comes amidst reports that a new migrant caravan from Honduras comprising about 1600 people is moving towards the US via Guatemala.

The caravan, formed in the Honduran city of San Pedro Sula on Saturday, crossed into Guatemala on Monday. Guatemala detained one of its coordinators on Tuesday, but other members of the caravan are advancing through Guatemala with hopes of reaching the US border.

"Anybody entering the United States illegally will be arrested and detained, prior to being sent back to their country!" Trump said in a late-night tweet.

He said his administration has informed the three countries - Honduras, Guatemala and El Salvador that America will stop all payments to them if they allow their citizens to enter the US.

"We have today informed the countries of Honduras, Guatemala and El Salvador that if they allow their citizens, or others, to journey through their borders and up to the United States, with the intention of entering our country illegally, all payments made to them will STOP (END)!" Trump said in another tweet.

In 2017, the US gave USD 248 million to Guatemala, USD 175 million to Honduras and USD 115 million to El Salvador in foreign aid.

Vice President Mike Pence also tweeted earlier, saying that he had spoken with Honduran President Juan Orlando Hernandez and Guatemalan President Jimmy Morales.

He said Trump's message to Honduras also applied to Guatemala, "no more aid if it's not stopped!"
