Earlier, a strong aftershock rocked the capital, Port-au-Prince, but did not seem to cause further casualties人员伤亡 there.

Away from the city, survivors³ in some towns are still waiting for help after the original 7.0-magnitude earthquake struck eight days ago.

The BBC's Mark Doyle, who visited the village of Leogane near the epicentre震中, said the only outside medical help it had seen was a team of Dominican and Spanish doctors who were setting up a treatment centre.

He said the village had been left looking worse than most war zones - as if it had been carpet-bombed, then pounded with a relentless无情的，残酷的 artillery⁵大炮，火炮 barrage⁶.

Haitian officials say the death toll死亡人数 from the quake was likely to be between 100,000 and 200,000, and that 75,000 bodies had already been buried in mass graves. An estimated 1.5 million are homeless.

People are still being found alive in the rubble碎石，碎砖, including a five-year-old boy reportedly pulled from the ruins of his home by his uncle. Earlier a 10-year-old girl and her eight-year-old brother were found.

More than 120 people altogether have been rescued by international teams.
