PORT-AU-PRINCE, Haiti (AP) - Haitian police fired at supporters of former president Jean-Bertrand Aristide on Monday, marking the one-year anniversary of a rebellion that ousted the democratically elected leader. At least two people were killed.

Protesters charged a police roadblock in Bel Air, a stronghold for Aristide militants where the anniversary protest began. The police fired tear gas, then bullets.

People with eyes streaming from tear gas ran off with one body and UN peacekeepers surrounded the second, which lay in a pool of blood. About a dozen were wounded.

Earlier, the crowd of some 2,000 had shouted slogans against U.S. President George W. Bush, whom Aristide blames for his ouster on Feb. 29. U.S. officials deny the claims.

"George Bush is the biggest terrorist!" the crowd yelled before shots rang out.

U.S. troops arrived in Haiti the day Aristide fled and remained until June, when they handed over to a UN force, now with about 7,400 troops under the command of Brazil.

"The people are revolting only to ask for what they voted for," said Rev. Gerard Jean-Juste, a friend of Aristide who was jailed last year.

Prime Minister Gerard Latortue's interim government denies that it has embarked on a witchhunt of Aristide supporters. Still, hundreds are jailed without charge, including former prime minister Yvon Neptune and former Interior Minister Jocelerme Privert.

The country plans general elections in October and November, but many groups are asking how the government will provide security.

Nearly 100 parties have registered to participate in the elections, though Aristide's Lavalas Party, which has the support of a vast majority of Haitians, has refused to participate unless its members are released from jail and security is ensured.

For more than a year before Aristide fled, popular protests grew against his increasingly repressive and corrupt government. Last February, a street gang in Haiti's third city of Gonaives, blaming Aristide for the assassination of its leader Amiot Metayer, led a popular revolt, torching the police station, killing officers and hunting down Aristide officials and followers.

The gangsters were joined by ex-soldiers from the army that Aristide had disbanded in 1995, a small but well-armed group that crossed from neighbouring Dominican Republic.

In three weeks, the rebels had overrun most of Haiti and were advancing on the capital when Aristide, refused support from the international community, fled the country.

People rioted, torching businesses, looting and burning homes and schools and shops shut down for weeks.

Order was restored by U.S. soldiers who arrived the day Aristide left and soon were joined by French and Canadian troops who helped install an interim government under Latortue, a former UN bureaucrat who was living in exile in Boca Raton, Florida.

Caribbean leaders refuse to recognize Latortue's government and have called in vain for an international investigation of Aristide's charges of regime change against the United States.

After Aristide left, the United States said it did not help him because he was taking money from drug traffickers - charges Aristide denies.

A year later, the U.S. Drug Enforcement Agency says the country remains a major transshipment point for drugs to the United States, and Haiti's eight million people remain in the grip of poverty, fear and political paralysis.
