A week after a 7.0-magnitude earthquake struck the island nation of Haiti, search and rescue crews have found dozens of survivors. However, the U.N. estimates the number of casualties in the capital city of Port-au-Prince alone from 100,000 to 150,000.

Security is now the key issue as people are scrambling following the devastation. On Monday, the U.N. Security Council voted to send 3,500 more peacekeepers to Haiti to assist in the relief effort, while the Pentagon announced there are about 1,700 troops in Haiti, with an estimated 5,000 soldiers and Marines expected to be in the country later this week.

Support has been pouring in for the impoverished nation. The American Red Cross has raised nearly $112 million dollars for Haiti relief efforts. President Abdoulaye Wade of Senegal has offered free land to people affected by the earthquake, saying “If it’s just a few individuals, then we will likely offer them housing or small pieces of land. If they come en masse we are ready to give them a region.”

“Hope for Haiti“, a global concert and telethon to raise money, will be co-hosted by Haitian-born Wyclef Jean and George Clooney and will air on ABC, BET, CBS, FOX, HBO, MTV, NBC and VH1 starting at 8 p.m. ET/PT this Friday (January 22).

Speaking of Wyclef, he took to YouTube to address allegations that his Yele Haiti Foundation mismanaged donations.

At a press conference in New York, Wyclef admitted the organization has “made mistakes”, but he insisted that he has never personally benefited from the foundation’s work:

“As a young NGO, have we made mistakes?” Jean asked in New York yesterday. “Yes. Did I ever use Yele money for personal benefits? Absolutely not.” Showing his Haitian passport and US green card, the former Fugees member emphasised that he founded the charity with his own funds. “I wanted to make sure that Yele would not just be a foundation, but would actually be an NGO on the ground in Haiti because it’s the only way I could be effective to the Haitian people.
