MOSCOW, November 27. /TASS/. The United States’ taskforce in Syria has blocked a 55-kilometer area around the US base at at-Tanf, with more than 50,000 people staying inside it, the Russian Defense Ministry said on Monday.

Despite the earlier consultations, the US side has given international organizations no access to the Rukban refugee camp to deliver relief aid, the ministry said.

"Having closed a 55-kilometer zone around the US base at at-Tanf, the US force has created a territory where, according to various estimates, more than 50,000 people are staying in isolation. It is an unprecedented situation of long-lasting hindrance to humanitarian assistance to those in need. The refugee camp is deprived of the possibility to have enough food and professional medical assistance, to ensure classes to children," the ministry said.
