The White House has said horses will no longer be used along the US border after images surfaced of a US border guard on horseback attempting to capture a Haitian migrant.

White House press secretary Jen Psaki condemned the US border patrol agents' use of reigns to intimidate migrants trying to cross the river and said an investigation is in progress.

This incident comes in the wake of the worsening situation in Haiti, which in recent weeks has been hit by a major earthquake and is still reeling from a presidential assassination.
