"As of mid-December, the Shelter Cluster, a coordination group of UN, international and local humanitarian organizations, estimates at least 945,000 still urgently need winterization assistance, such as thermal clothing, blankets, and tarps to seal-off shelters from the rain and cold," it said.
The agency reiterated its call for a cease-fire to enable the safe and immediate delivery of life-saving aid to those in desperate need.
"IOM also renews its call for all parties to adhere to international humanitarian law, ensure the protection of civilians, release of all hostages and allow safe, rapid, unimpeded and sustained humanitarian access," it said.
