The UN humanitarian coordinator for Gaza, Sigrid Kaag, said on Tuesday that 1.9 million people were now displaced in the territory, adding that she was "deeply concerned" by reports of a new evacuation order for Khan Yunis. 

She made the remark at a UN Security Council meeting on the situation in the Middle East.

The Israeli army on Monday issued a new evacuation order for parts of Khan Yunis and Rafah in southern Gaza.
