Eight of the 10 missionaries from Boise, Idaho who were charged with trying to take Haitian children out of the country illegally have been freed and are now back in the U.S. They were released by a Haitian judge on Wednesday, nearly three weeks after they were jailed for trying to take a group of children out of the earthquake-stricken country.

After the quake, help can't come fast enough as Haitians wait for basic needs, like water and food, to reach them. 12,000 U.S. troops are expected to be on the ground in Haiti by the end of the day. 100,000 is the expected death toll right now. The BBC's Nick Davis describes the stepped up relief effort and updates the security situation.
