Trump threatens to close southern border next week

WASHINGTON, March 29 (Xinhua) -- U.S. President Donald Trump on Friday threatened to close the nation's southern border with Mexico next week, amid feud over illegal immigration.

"If Mexico doesn't immediately stop ALL illegal immigration coming into the United States through our southern border, I will be closing the border, or large sections of the border, next week," Trump said on Twitter.

The threat comes a day after Trump criticized Mexico and several Central American nations for not halting illegal immigrants heading north to cross the U.S. border.
