UNITED NATIONS, April 4 (Xinhua) -- The United Nations on Wednesday voiced deep concern over the safety and protection of civilians from Eastern Ghouta who continue to be displaced from their areas of origin, as well as those who remain in the besieged enclave, said a UN spokesman on Wednesday.

Since March 9, an estimated 133,000 people have left Eastern Ghouta, either through established corridors to internally displaced persons (IDP) sites in rural Damascus or through evacuation agreements to Idlib and Aleppo governorates, said Stephane Dujarric, the spokesman.

As of Tuesday, some 44,000 people remain in eight IDP sites in rural Damascus, down from a peak number of 83,000. But most shelters still largely exceed their capacity, he said.

While some assistance is being provided to the population remaining in newly accessible areas, there has been no access to the besieged area of Douma since the last inter-agency convoy reached the area on March 15, said the spokesman.

The United Nations and partners are also facing serious funding gaps to respond with life-saving assistance and protection services, he said.

In Afrin, where Turkish troops are pursuing a military campaign against the Kurds, the gradual return of IDPs reportedly continued mainly from Nabul and Zahraa, and a smaller number from Tal Refaat toward Afrin district, but exact figures are not yet available, said the spokesman.

The United Nations continues to be concerned for the safety and protection of civilians impacted by hostilities in the area and reported restrictions of movement, he said.

An estimated 137,000 people have been displaced to Tal Refaat and to the surrounding villages due to recent fighting, he noted.
