A boy and a girl Wednesday were rescued in Port-au-Prince from under the rubble of the Haitian quake.

A five-year-old boy's uncle pulled him out of rubble and took him to a local hospital, eight days after the devastating quake.

The uncle said he luckily discovered the boy in a small void under the rubble of a house, but the boy's father and mother were believed to have died.

The boy apparently had no other harm, except being severely dehydrated and dysphoric.

Meanwhile, an 11-year-old girl was pulled out from under the rubble by her neighbors.

The girl was being treated at the Lambert clinic. She lay on a bed in the clinic's corridor, occasionally crying out with nightmares.

"It truly is a miracle, she came back to life bit by bit. She is blessed by the God," said surgeon Dominique Jean.

Earlier Wednesday, a UN spokeswoman in Geneva said international teams had rescued 121 people from the debris of collapsed buildings.

A 6.1-magnitude aftershock, the most powerful of the over 40 significant ones since the Jan. 12 temblor, jolted Port-au-Prince at dawn of Wednesday.

Haiti's Civil Defense Department Tuesday said the quake had killed 75,000 people, injured 250,000 others and left 1 million homeless.

Haitian officials said the final death toll may reach between 100,000 to 200,000.
