A new report by Human Rights Watch (HRW) has accused Saudi border guards of mass killings of migrants along the Yemeni border.
The report, titled "They Fired On Us Like Rain," says that hundreds of people, many of them Ethiopians, have been shot dead by Saudi security forces while trying to cross the border.
The report is based on interviews with survivors and satellite imagery of the border area. It details 28 separate incidents involving explosive weapons and 14 shootings at close range.
One survivor, Mustafa Soufia Mohammed, told HRW that he was shot in the leg while trying to cross the border with a group of 45 other migrants. He said that some of the people in his group were killed.
Another survivor, Zahra, said that she was shot in the hand while trying to cross the border. She said that she saw bodies strewn all over the hillside.
The report says that the killings are likely to be thousands and that they may amount to a crime against humanity.
The Saudi government has denied the allegations, saying that it takes them seriously but that it has found no evidence to support them.
The BBC has approached the Saudi government for comment but has not received a response.
The report is the latest in a series of allegations of human rights abuses by Saudi security forces. In recent years, the Saudi government has been accused of torture, arbitrary detention, and the use of excessive force against its own citizens.
The allegations of mass killings of migrants are particularly disturbing, and they raise serious questions about the Saudi government's commitment to human rights.
The international community must take action to investigate these allegations and hold those responsible to account.
