United Nations, Sep 18 (TIWN) The UN Office for the Coordination of Humanitarian Affairs (OCHA) said they were working not only to get more relief convoys into Ethiopia's conflict-hit Tigray region but also to get empty delivery trucks out.

"The UN is urgently engaging with all parties, including transporters and local authorities in Tigray, to make sure any logistical issues that may be preventing the trucks from leaving Tigray are resolved, at the same time as working to make additional trucks available for the aid operation," the OCHA said.  In the latest obstacle to humanitarian operations in Ethiopia's northernmost area, the office said some trucks that successfully got into embattled Tigray face challenges returning for more loads of aid cargo.  Drivers reluctant to take to the road back fear for their safety or are short on fuel, OCHA said.
