The UN on Friday launched an emergency aid appeal seeking $1.2 billion to help some 2.7 million people in Gaza and the West Bank.
"The cost of meeting the needs of 2.7 million people - that is the entire population of Gaza and 500,000 people in the occupied West Bank - is estimated to be $1.2 billion," the Office for the Coordination of Humanitarian Affairs (OCHA) said.
"The original appeal, launched 12 October, asked for $294 million to support nearly 1.3 million people. The situation has grown increasingly desperate since then," it added.
