Prime Minister Ariel Henry said on Sunday that it was necessary to "work together" in the face of the "extremely serious situation" following the earthquake, which has also left some 5,700 injured, reports Xinhua news agency.

"As soon as I landed, I met victims of the earthquake. Doctors, rescuers, and paramedics are arriving to provide assistance from the Cayes airport. "A harsh and sad reality that we must face with courage," the Prime Minister said on Twitter.

He noted that various teams are on the ground to "provide help and assistance to victims" and called for a speedy action to respond to the crisis.

The 7.2-magnitude earthquake on Saturday struck about 12 km from the southern town of Saint Louis du Sud in the southwestern part of Haiti, about 150 km from the capital of Port-au-Prince.
