Venezuela and Colombia have withdrawn their ambassadors due to a diplomatic crisis over Venezuela's treatment of Colombian immigrants.

Venezuelan President Nicolas Maduro shut two border crossings last week after a firefight between Venezuelan soldiers and Colombian smugglers left three soldiers wounded. President Maduro later announced that the closings would be permanent and deported over a thousand Colombians.

Colombia responded by withdrawing its ambassador to the neighboring country. "These families aren't paramilitaries, they are humble families," Colombian President Juan Manuel Santos said. "And they were thrown out, as they said to me, like dogs."

This led to Venezuela also recalling its ambassador to Colombia.
