As he met by angry Haitians protesting the slow arrival of help since last month's quake, former US president Bill Clinton pledged Friday to try to get aid flowing quickly.Clinton said he was sorry that the aid efforts had been so slow, adding he also wanted to understand why more than three weeks after the January 12 quake supplies were still not getting through to desperate Haitians. "I'm sorry it's taken this long," Clinton said, adding he and other relief workers were working hard to ease the suffering.But the former president rejected suggestions he had in effect become governor of this small Caribbean nation. "What I don't want to be is the governor of Haiti. I want to build the capacity of the country to chart its own course. They can trust me not to be a neocolonialist, I'm too old."Clinton also visited the government's de facto headquarters in a police building in the city, where people demonstrated outside to protest the lack of shelter. Other protesters gathered in front of the US embassy nearby.Participants said they hoped to meet Clinton, who was designated Wednesday as coordinator of international aid for the impoverished Caribbean nation by UN Secretary General Ban Ki-moon.But his visit threatened to be overshadowed by the case of 10 American Christians detained on child kidnapping charges for trying to smuggle 33 Haitian children across the border into the Dominican Republic.Clinton stressed he was not there to intervene in the case. "That's not within my mandate. I know that the State Department and government have had these discussions."The five men and five women were sent to jail on Friday to await trial, after being charged with child abduction and criminal conspiracy by Haitian prosecutors on Thursday. The Haitian authorities, under pressure to clamp down on child trafficking and to show the country's crippled government can get on its feet, have insisted the 10 should be tried in Haiti.Clinton's wife, US Secretary of State Hillary Clinton, said Friday the US ambassador was working with Haitian officials on the case, and that Washington expressed "hope that this matter can be resolved in an expeditious way." "Obviously, this is a matter for the Haitian judicial system," she added.An estimated 212,000 people were killed by the 7.0 magnitude earthquake, making it the worst recorded natural disaster in the Americas.The United States, which is spearheading the relief efforts, has deployed 20,000 troops plus helicopters, transport planes and other equipment.
