Border guards in Saudi Arabia fired machine guns and launched mortars at Ethiopians trying to cross into the kingdom from Yemen, likely killing hundreds of the unarmed migrants in recent years, Human Rights Watch said in a report released Monday.
The rights group cited eyewitness reports of attacks by troops and images that showed dead bodies and burial sites on migrant routes, saying the death toll could even be "possibly thousands."
The United Nations has already questioned Saudi Arabia about its troops opening fire on the migrants.
Saudi officials did not respond to requests for comment from The Associated Press, but has previously denied its troops killed migrants.
Some 750,000 Ethiopians live in Saudi Arabia, with as many as 450,000 likely having entered the kingdom without authorization, according to 2022 statistics from the International Organization for Migration. The two-year civil war in Ethiopia's northern Tigray region displaced tens of thousands of people.
Saudi Arabia, struggling with youth unemployment, has been sending thousands back to Ethiopia in concert with Addis Abba.
Human Rights Watch said it spoke to 38 Ethiopian migrants and four relatives of people who attempted to cross the border between March 2022 and June 2023 who said they saw Saudi guards shoot at migrants or launch explosives at groups.
The report said the group also analyzed over 350 videos and photographs posted to social media or gathered from other sources filmed between May 12, 2021, and July 18, 2023. It also examined several hundred square kilometers (miles) of satellite imagery captured between February 2022 and July 2023.
"These show dead and wounded migrants on the trails, in camps and in medical facilities, how burial sites near the migrant camps grew in size, the expanding Saudi Arabian border security infrastructure, and the routes currently used by the migrants to attempt border crossings," the report said.
An April 27 satellite photo from Planet Labs PBC analyzed by the AP showed the same tent structures identified by the rights group near al-Raqw, Yemen, on the Saudi border. Two sets of fence lines could be seen just across the border into Saudi Arabia.
The site Human Rights Watch identified as the migrant camp at Al-Thabit also could be seen in satellite images, which corresponded to the group's narrative that the camp largely had been dismantled in early April.
