Six months into a deadly conflict that has killed more than 2,100 civilians and created a humanitarian catastrophe in Yemen, Amnesty International said on Friday that the UN Human Rights Council should establish an investigation into violations of international humanitarian law and human rights in Yemen.

More than 2,100 civilians have been killed, including some 400 children, during the Saudi led Attacks in Yemen, while more than 1.4 million people have been displaced. The conflict has created a humanitarian disaster that has left some 80 percent of the population in need of humanitarian assistance.

Amnesty International and other organizations has documented numerous violations of the conflict, some of which may amount to war crimes. However, Amnesty said the "vast majority of civilian deaths and injuries have been caused by the Saudi Arabia-led coalition which is backed by the USA and the UK."

The US has provided intelligence, logistics and refueling support, and military assistance to the Saudi-led coalition air campaign.

Documented violations include indiscriminate airstrikes on civilians, the destruction of homes, schools and mosques, as well as the targeting of roads and bridges, which have compounded the difficulty of delivering humanitarian supplies. The Saudi-led coalition has also implemented a naval blockade, further hampering the delivery of humanitarian supplies.

"Coalition forces have also used banned cluster munitions, which are indiscriminate by nature, and have been found to be produced or designed in the USA," Amnesty said.

"The organization is urging the creation of a UN Commission of Inquiry into violations and abuses committed to the Yemen conflict, at the current Human Rights Council session in Geneva which concludes on 2 October," Amnesty said in a statement.

In March, Saudi Arabia alongside Sunni Arab states launched a military campaign to oust Houthi Popular movement, who took the capital Sanaa in September 2014. Houthi Popular movement saying they are fighting corruption and want to reform the political system.

Amnesty International's call for an investigation into the war in Yemen comes as the Netherlands on Thursday submitted a resolution to the UN Human Rights Council to create a fact-finding mission in Yemen.
