"The United States, United Kingdom, France and others should suspend all weapon sales to Saudi Arabia until it not only curtails its unlawful airstrikes in Yemen, but also credibly investigates alleged violations," Human Rights Watch said in a news release on Monday.
Since March 26, 2015, a Saudi-led coalition of mostly Arab countries has conducted military operations against the Houthi armed group in Yemen, and has carried out numerous indiscriminate and disproportionate airstrikes, Human Rights Watch stated.
"For the past year, governments that arm Saudi Arabia have rejected or downplayed compelling evidence that the coalition’s airstrikes have killed hundreds of civilians in Yemen," Human Rights Watch Deputy Global Advocacy Director Philippe Bolopion said in the release.
The airstrikes have continued despite the March 20 announcement of a new ceasefire, Human Rights Watch claimed, and the Saudi-led coalition has consistently failed to investigate alleged unlawful attacks.
Saudi Arabia has been the leader of the coalition, with targeting decisions made in the Saudi Defense Ministry in Riyadh, according to the release.
At least 3,200 civilians have been killed and 5,700 wounded since coalition military operations began, 60 percent of them in coalition airstrikes, according to the UN High Commissioner for Human Rights.
