MOGADISHU, Nov. 1 (Xinhua) -- The UN top envoy in Somalia has cautioned that a stand-off between Somali government and regional leaders could scuttle international community's efforts to stabilize the Horn of Africa nation.

Nicholas Haysom, United Nations Secretary-General's Special Representative for Somalia, renewed his call for collaboration to solve ongoing tensions between the country's federal and state authorities.

"We are exploring ways of bringing them together in the hope that Somalis can face down their problems together rather than going separately," Haysom said in a statement issued by the UN Mission in Somalia on Wednesday night.

The UN envoy's remarks come as political impasse continues after leaders of five Somali regional states on Sept. 8 suspended relations with the central government due to lack of political and security progress in the Horn of Africa nation.

The leaders from Jubaland, Puntland, Southwest, Galmudug and Hirshabelle regions accuse the government of interfering with regional issues, failure to implement security architecture and not fulfilling political agreements.

"Basically, we have been telling them that what we are facing is a quite serious political issue - the stand-off between the Federal Member States and the Federal Government may well paralyze our efforts to help Somalia get back on its feet," he added, according to the statement.
