President Bill Clinton, in an interview with Fox News' Greta Van Susteren, said the next 10 days are the most critical for the rescue efforts in Haiti after a magnitude-7.0 earthquake rocked the country Tuesday.

For "three or four more days, we can still find people alive," Clinton, the U.N. envoy to Haiti, said Wednesday. "The most important thing now is we have got to get people out from under this rubble."

Within the next 10 days, Clinton said efforts will focus on "saving every life we can, and treating the dead with respect so they get a decent burial."

He urged Americans to not travel to Haiti in hopes of helping, but instead make donations that will help supply relief efforts with what they need most — food, water, shelter and first aid supplies.

"Every $5 or $10 immediately is moved to buy basic medical supplies and to take care of them," Clinton told Fox News.
