The transitional leader of Central African Republic says the security situation is improving in his coup-plagued country, despite reports to the contrary from aid groups.

During a visit to Burkina Faso on Monday, Michel Djotodia said the biggest security threat came from the Lord's Resistance Army, a notorious rebel group led by Joseph Kony that has operated in the country for years.

Djotodia became interim leader in March after his Seleka rebel coalition deposed former President Francois Bozize.

Human Rights Watch has accused Seleka of destroying dozens of villages since February, and aid groups have accused the international community of ignoring the humanitarian crisis in the nation of 4.6 million.

Djotodia made no mention of Seleka abuses but said peace had been restored to the capital, Bangui.
