海地地震发生后，首都太子港屡有抢掠事件发生，治安状况令人堪忧。因当地一所大型监狱在地震中被毁，目前有数千名监狱犯人下落不明，部分安全逃出的犯人已被再次拘捕。另外，由于海港、公路及其它基础设施被毁，导致各国运往海地的救援物资滞留机场无法迅速下发到各地受灾民众手中，普通民众为哄抢有限的救援物资而成为了治安骚乱事件的另一组成部分。联合国人道主义事务协调办公室发言人表示，此次海地地震造成的破坏情况要比2004年印尼海啸还要严重，当初给印尼援助的时候至少还能得到当地政府的协调支持，而海地多数政府建筑在地震中被毁，致使政府机构瘫痪，无法为援助工作提供支持。

　　There are mounting security concernsin Haiti's earthquake-hit capital as distribution problems continue to hamper getting aid to survivors。

　　Days after the quake devastatedPort-au-Prince, killing tens of thousands, there are some reports of gangs preying on residents and looting。

　　Officials say thousands of prisoners are unaccounted for after the main prison was destroyed。

　　Relief has been arriving, but little has moved beyond the jammed airport。

　　Damage to the seaport, roads and other infrastructure has prevented the speedy distribution of food, water and medical supplies。

　　On Saturday morning, a magnitude-4.5 aftershock struck close to Haiti's capital, the US Geological Survey said, forcing people to flee buildings。

　　US President Barack Obama met two of his predecessors in the White House, George W Bush and Bill Clinton, to seek their support。

　　After the talks, Mr. Obama said the two men would lead the US' fundraising efforts through the Bush-Clinton Haiti Fund。

　　"America is moving forward with one ofthe largest relief efforts in its history," Mr. Obama said, warning that recovery would take a long time。

　　President Bush urged Americans to send"cash", and President Clinton said Haitians "can escape their historyand built a better future if we do our part"。

　　US Secretary of State Hillary Clintonis travelling to Haiti on Saturday to assess the damage and convey tothe Haitian people "our long term, unwavering support, solidarity and sympathies"。

　　A spokeswoman for the UN Office forthe Co-ordination of Humanitarian Affairs said aid workers were dealingwith a disaster "like no other" in UN memory because the country hadbeen "decapitated"。

　　"Government buildings have collapsedand we do not even have the support of the local infrastructure,"Elisabeth Byrs said in Geneva。

　　Ms Byrs said the situation was even worse than the devastation wrought by the 2004 tsunami in Indonesia's Aceh province。

　　"It's worse than the Indonesian earthquake where at least we could get the support of some local authorities," she said。

　　Arrests

　　Desperation among survivors of Tuesday's earthquake has led to rising fears over security in Port-au-Prince。

　　"Men suddenly appeared with machetes to steal money," resident Evelyne Buino told AFP news agency。

　　Up to 4,000 prisoners are unaccounted for, with many believed to have escaped from the central prison。

　　"There are thieves coming out," Haitian police inspector-general Jean-Yonel Trecile told Reuters news agency。

　　"To make sure this does not spread, we have taken a number of these people off the streets. We have arrested about 50 people."

　　There is little police presence in the capital, although some Brazilian UN peacekeepers are patrolling the streets。

　　UN Undersecretary General forPeacekeeping Alain Le Roy told the US Public Broadcasting Service (PBS)network on Friday: "There have been some incidents where people werelooting or fighting for food. They are desperate."

　　But he added that overall the situation remained under control so far。
