Air attack on Saudi Arabian oil plants

The drone attack, or assault by unmanned aircraft, on Saudi Arabian oil plants has reduced productivity by 50%. Responsibility for this has been admitted by Yemen. The reason surely being Saudi involvement in the taking of Yemen’s oil without consent. The US are also involved, and although this is reported to be a two-fold joint venture, various reports tell of air strikes on Yemen from the UK, France, China and Russia. This constitutes the UN security council.
Yemen is in crisis and indigenous Houthis have been termed rebels because they are fighting for their oil. There are reports of blockades concerning humanitarian aid. The US is blaming Iran. The UN are calling The situation in Yemen a civil war, and last year warned that 13 million Yemenese were facing starvation.
