Leaders of the East African Community (EAC) have been urged to expedite the deployment of more soldiers to the regional force operating in the eastern Democratic Republic of the Congo.
According to the Luanda ceasefire agreement, more troops are required to take up positions in areas where armed groups have evacuated, according to former Kenyan president and mediator Uhuru Kenyatta for the East African Community (EAC) bloc.
Mr. Kenyatta expressed worry about the deteriorating security situation in the province of North Kivu, where M23 rebels have recently clashed with security forces.
After Burundi and Kenyan contingents arrived in eastern DR Congo last year to help end decades of instability, Uganda and South Sudan are preparing to send troops.
Mr Kenyatta welcomed recent calls by East African leaders for the cessation of hostilities by all sides in the conflict.
In a statement, the facilitator said he would intensify plans for the fourth round of talks in Nairobi by mobilising regional and international support for the meeting.
He has urged all parties involved to accelerate implementation of resolutions of the third consultative talks in Nairobi.
He has also appealed for urgent humanitarian support to more than half a million people displaced by the conflict in North Kivu province.
The conflict has strained relations with the DR Congo, which accuses neighbouring Rwanda of backing the M23 rebels. Rwanda denies the accusations.
