President Trump warned Mexico that armed soldiers will be sent to the border following an incident where Mexican soldiers held U.S. soldiers at gunpoint on U.S. soil.

According to Fox News:

President Trump on Wednesday warned Mexico after their soldiers reportedly drew guns on U.S. troops at the border last week, while also calling on America’s southern neighbor to do more to halt another north-bound migrant caravan.

“Mexico’s Soldiers recently pulled guns on our National Guard Soldiers, probably as a diversionary tactic for drug smugglers on the Border. Better not happen again! We are now sending ARMED SOLDIERS to the Border. Mexico is not doing nearly enough in apprehending & returning!” he tweeted.

The president’s tweets come after several Mexican military personnel reportedly questioned U.S Army soldiers who were on patrol duty near the border in Texas. Mexican soldiers reportedly pointed their weapons at U.S. troops during the encounter. The Mexican soldiers reportedly believed that the U.S. Army soldiers were on Mexican territory.

The president of the National Border Patrol Council, Brandon Judd, said over the weekend that “these things don’t just happen by accident.”

It is speculated that the Mexicans knew they were on U.S. soil. President Trump also warned of a new caravan approaching the U.S. border.
