Almost a quarter of a million people have died in Yemen's war, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said on its website on Tuesday, confirming the huge toll from a conflict that has ravaged Yemen's economy and created the world's worst humanitarian crisis.

OCHA included the figure in an update within its latest Global Humanitarian Overview, where it gave a description of the context, crisis and humanitarian needs in Yemen. It said the conflict had intensified this year, with 47 identifiable front lines by the end of October, up from 33 at the start of this year.

"The war had already caused an estimated 233,000 deaths, including 131,000 from indirect causes such as lack of food, health services and infrastructure", it said.

Over 3,000 child deaths

"Hostilities have directly caused tens of thousands of civilian casualties; 3,153 child deaths and 5,660 children were verified in the first five years of the conflict, and 1,500 civilian casualties were reported in the first nine months of 2020."

The chief UN humanitarian official in Yemen, Altaf Musani, the acting Humanitarian Coordinator for Yemen, said in a statement on Tuesday that there had been artillery shelling of residential areas in the city of Taizz, a violation of international law. Preliminary reports indicated that two children had been killed, with a further three children and four women injured.

"These senseless attacks, with so many children and women casualties, are horrific and inexcusable,”Mr. Musani said. "Today, more families are grieving for children who died needlessly.”

UNICEF said 11 children, including a one-month old baby, had been killed in the past three days, in separate attacks in Taizz and Al Hudaydah govenorate.

"Verification is still ongoing, and the actual number of casualties may be higher", Philippe Duamelle, UNICEF Representative to Yemen, said in a statement.

"The killing of children is appalling. Children should be protected at all times."

Yemen's complex civil war began in earnest in 2015, foisting disease, hunger and economic collapse on an already impoverished population. In 2020 the violence escalated and the hardship deepened with torrential rains, a fuel crisis, COVID-19 and desert locust infestations that are expected to cause damage and loss worth $222 million to staple crops, animals and livestock.

'Imminent catastrophe’

In October UN Secretary-General António Guterres warned that Yemen was in “imminent danger of the worst famine the world has seen for decades" and Henrietta Fore, head of the UN Children’s Fund (UNICEF), said the country was facing "an imminent catastrophe".

UNICEF's humanitarian appeal for Yemen for 2020, requiring $535 million, has received just $237 million – a funding gap of almost $300 million.

OCHA said it was very difficult to bring aid into Yemen, citing an extremely restricted operating environment and a huge funding shortfall that had crippled the humanitarian response.
