Doctors in Haiti on Monday battled in makeshift tents to save the lives of hundreds of victims, including young children and older people, outside hospitals overwhelmed by an earthquake that killed at least 1,419 people.

While rescue teams toiled to dig out survivors of Saturday's 7.2 magnitude quake, a storm dumped heavy rain on the southern coast of Haiti, bringing flooding near the worst-hit areas and exacerbating the humanitarian crisis, local residents said.

Deus Deronneth, a politician from the Jacmel region, posted a video on Twitter showing a torrent of water sweeping through a local town and confirmed the flooding to Reuters.
