After Preval won election in February, the level of violence in Haiti dropped sharply. But its resurgence has prompted U.N. Secretary-General Kofi Annan, who visited Port-au-Prince last week, to advise the Security Council against curtailing the U.N. peacekeeping force.
At least 100 people have been shot dead in the capital Port-au-Prince over the last two months and about 400 others have been injured by gunshots, according to hospital records cited on Thursday by Ronald Lareche, who heads the Public Safety Committee of the lower house of parliament.
He said the death toll, from what were mostly believed to be gang-related shootings, included 85 victims in July alone.
Government officials have said drug lords were now seeking to bankroll armed gangs, to win de facto control over them and block any disarmament plans.
The violent status quo in Haiti provides good cover for trafficking in narcotics, the officials say.
"They (drug kingpins) want to make sure the chaotic situation endures so that they may continue to carry out their dirty work," Alexis said.
Gang leaders have made tentative offers to disarm in the past, including one last week from the young toughs who control Haiti's largest slum, but none of them have come to fruition so far.
