Thousands of tsunami victims in Sri Lanka are slowly returning to government-run centers a day after flash floods forced them out.
The floods are also slowing down relief efforts. Aid convoys continue to have difficulty reaching some of the hardest-hit areas on the devastated eastern coast.
Health officials say they are bracing for outbreaks of contagious diseases as hundreds of thousands of displaced people live in unsanitary conditions and lack clean drinking water.
Aid continues to arrive from other countries. The first contingent of 1,500 U.S. Marines, along with a ship carrying 20 helicopters, are due to arrive in Sri Lanka later Sunday. The Marines will operate from an offshore platform south of the port city of Galle.
