The Office for the Coordination of Humanitarian Affairs (OCHA) says the security situation in Eastern Chad is getting worse, following an attack on a humanitarian convoy over the weekend.
Elizabeth Byrs, Spokesperson for the humanitarian agency speaking to reporters in Geneva on Monday.
"A new level of insecurity has been reached with the 20 December attack, on a convoy of the United Nations Mission in the Central African Republic and Chad (MINURCAT), escorted by the Integrated Security Detachment, D.I.S. in which one officer of the detachment was wounded. This attack took place on the road leading to Goz Beida in Koukou, east of Chad".
The detachment provides security in camps for refugees and internally displaced persons, as well as for the activities of humanitarian organizations.
All transport except for ambulances has now been suspended on the roads where the attack took place.
Byrs notes the attack represents a new level in banditry where the assailants are now brazen enough to attack humanitarian transports under security escort.
This constitutes a serious handicap for the future distribution of humanitarian assistance, she adds.
In Eastern Chad, the United Nations and its humanitarian partners are currently assisting more than half a million people, mainly refugees and internally displaced persons.
