**The number of people killed in the Haiti earthquake could be 230,000, the Haitian government says, revising its latest estimate up by 18,000.**Communications Minister Marie-Laurence Jocelyn Lassegue said the toll was not definitive. About 300,000 were injured.
The latest figure does not include bodies buried by private funeral homes in private cemeteries, or the dead buried by their own families.
The one-month anniversary is to be marked with prayer vigils and fasting.
The death toll from the 12 January quake is approaching that of the Asian tsunami of 26 December 2004, in which about 250,000 people died.
A BBC correspondent in the capital Port-au-Prince says there is increasing concern that with the rainy season approaching, the lack of tents and temporary shelter could lead to the outbreak of disease.
In the biggest of the camps that sprung up in the city after the earthquake, people are still living under sheeting strung across wooden poles.
Supermarket collapse
Aid agency officials said there was a plan to get thousands of the most vulnerable homeless people into tents ahead of the rains.
But the challenges of putting large numbers of tents in the crowded camps are considerable.
Meanwhile, there are reports that a damaged supermarket collapsed while people were inside.
Rescue teams, which had been retrieving bodies of quake victims from the site, tried to remove debris to reach an estimated five to eight people trapped underneath.
It was unclear if they were alive. They were allegedly looters, AFP news agency reported.
