The United Nations says it is seriously concerned that a group of former Maoist rebels in Nepal left their U.N. camp while carrying weapons.
On Monday, police detained 19 former fighters who were caught with arms outside their camp.
A U.N. statement issued Tuesday said the ex-rebels' actions violated the peace agreement signed by Nepal's government and Maoist rebels in 2006.
As part of that peace deal, thousands of former rebels have been living in U.N.-monitored camps.
The peace agreement brought the former rebel Maoists into Nepal's mainstream politics after a decade-long insurgency that claimed about 13-thousand lives.
