BEIRUT: The U.N.’s refugee agency (UNHCR) has expanded its services to Syrian refugees in southern Lebanon and plans to begin registration in the region in the coming weeks, it said in its weekly briefing Friday. There are an estimated 7,500 Syrian refugees in southern Lebanon, and 4,000 have already requested registration appointments, according to the United Nations High Relief Commissioner. UNHCR’s activities have so far been focused in northern and eastern Lebanon. The body Friday announced a weekly increase of nearly 3,000 in the number of refugees it is currently aiding, to 67,960, of which 49,653 are registered. It also highlighted difficulties in funding secondary medical care for refugees. The body is committed to funding health care only until the end of October.
