Massive International Relief Begins to Arrive in Haiti Following Devastating Earthquake

International aid agencies report emergency operations for earthquake victims in Haiti are slowly gathering steam.

But, they say they are working under severe constraints and it will take time before essential, critical needs are met.

The United Nations reports the airport is open, but is congested and good coordination will be necessary to move relief goods to affected areas.

International aid groups estimate that the earthquake has affected three million Haitians, with the death toll expected in the tens of thousands. On Thursday, medical supplies, food and workers trickled in from aid agencies and other countries, but the wreckage of buildings, roads and utilities has slowed search and rescue work.
