More than 100 people died from starvation and disease over the last year in a government-run camp set up to house former rebels and their families in Democratic Republic of Congo, Human Rights Watch (HRW) said on Wednesday.

The group said the deaths were likely to discourage other insurgents still fighting government and U.N. forces in the east from signing up to any future programs to persuade them to disarm and settle.

A spokesman for Congo's government said an investigation had been launched into the situation but health problems that people face across Congo, rather than poor management at the camp, were most likely to be the cause of the deaths.
