A day after the US shutdown a port of entry on its southwestern border and shot tear gas and pepper spray into crowds of migrants to stop them from crossing illegally, Donald Trump has said Mexico should deport them back to their home countries.
Many of the approximately 5,000 migrants camped out in Tijuana, Mexico, are attempting to enter the US through the San Ysidro port near San Diego, California, in order to apply for asylum. US border agents are approving approximately 100 applications per day but tensions over the slow pace came to a head over the weekend.
Mr Trump - who also defended the use of tear gas - tweeted: "Mexico should move the flag-waving Migrants, many of whom are stone cold criminals, back to their countries. Do it by plane, do it by bus, do it anyway you want, but they are NOT coming into the U.S.A. We will close the Border permanently if need be. Congress, fund the WALL!"
Later, Mexico's foreign ministry presented a diplomatic note to the US government calling for "a full investigation" into what it described as non-lethal weapons directed towards Mexican territory on Sunday, a statement from the ministry said.

Mexico has been in negotiations with the United States over a possible scheme to keep migrants in Mexico while their asylum claims are processed.
The team of Mexican President-elect Andres Manuel Lopez Obrador, who takes office on Saturday, says no deal has been agreed on the migrants. But officials are hinting they could remain.
"We should be objective, whatever happens they will stay in Mexico," said Alejandro Encinas, incoming deputy interior minister. "Migrants have rights and we will respect them."
