The UN human rights office (OHCHR) said strikes hit homes, markets, hospitals, displacement sites, power stations and water sources in Kordofan, Darfur, Blue Nile, Khartoum and other states. Drones already account for the majority of conflict-related civilian deaths in Sudan this year, according to the office.
"The increasing use of drones, already accounting for the majority of conflict-related civilian deaths in Sudan this year, is deeply disturbing and is exacting a horrifying toll," Mr Türk said.
In what the office described as a disturbing trend, it documented numerous strikes on displacement sites where people who had already fled the fighting had sought shelter. Between 6 and 10 October, alleged drone strikes attributed to military government forces on shelters for displaced people in Ghubeish and El Nuhud in West Kordofan killed at least 25 civilians, including women and children.
On 9 October, an alleged RSF drone struck a crowd of displaced people engaged in artisanal gold mining near a displacement site in Abu Shendi, Blue Nile, killing at least 31 people, most of them women and children. On 18 October, at least 139 people were killed when a transportation truck was hit in a "double tap" repeat strike in Dibab, West Kordofan, an area controlled by the RSF.
Markets and hospitals have also been hit, including an RSF-attributed strike on Um Darfa hospital in Blue Nile on 11 October that seriously injured two health workers and left the facility non-operational.
"Scores of civilians have been killed, including internally displaced persons, and vital infrastructure and services have been eviscerated, driving further displacement and deepening the already severe humanitarian crisis," said OHCHR spokesperson Seif Magango.
Mr Türk called on the parties to respect their obligations under international humanitarian law, including by not directing attacks against civilians and civilian objects. He urged both parties and their affiliates to commit to a ceasefire, and said broader peace efforts must address the continued influx of arms fuelling the conflict and press for an end to transfers of arms used in manifest disregard of the law protecting civilians.
