Khartoum massacre: In Sudan, over 100 people are killed when security forces accompanied by Janjaweed militiamen storm and open fire on a sit-in protest.

The Khartoum massacre occurred on 3 June 2019, when the armed forces of the Sudanese Transitional Military Council, headed by the Lieutenant-General Abdel Fattah Abdelrahman Burhan of the Sudan Armed Forces and his deputy, Mohamed Hamdan Dagalo of the Rapid Support Forces (RSF), the immediate successor organisation to the Janjaweed militia, used heavy gunfire and tear gas to disperse a sit-in by protestors in Khartoum, killing over 100 people, with difficulties in estimating the actual numbers. At least forty of the bodies had been thrown in the River Nile. Hundreds of unarmed civilians were injured, hundreds more were arrested, many families were terrorised in their home estates across Sudan, and the RSF raped more than 70 women and men. The Internet was almost completely blocked in Sudan in the days following the massacre, making it difficult to estimate the number of victims.

Sudan, officially the Republic of Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopia to the southeast, and South Sudan to the south. Sudan has a population of 50 million people as of 2024 and occupies 1,886,068 square kilometres, making it Africa's third-largest country by area. Sudan's capital and most populous city is Khartoum.

The Janjaweed are an Arab nomad militia group operating in the Sahel region, specifically in Sudan, particularly in Darfur and eastern Chad. They have also been speculated to be active in Yemen. According to the United Nations definition, Janjaweed membership consists of Arab nomad tribes from the Sahel, the core of whom are Abbala Arabs, traditionally employed in camel herding, with significant recruitment from the Baggara.

The Sudanese revolution was a major shift of political power in Sudan that started with street protests throughout Sudan on 19 December 2018 and continued with sustained civil disobedience for about eight months, during which the 2019 Sudanese coup d'état deposed President Omar al-Bashir on 11 April after thirty years in power, 3 June Khartoum massacre took place under the leadership of the Transitional Military Council (TMC) that replaced al-Bashir, and in July and August 2019 the TMC and the Forces of Freedom and Change alliance (FFC) signed a Political Agreement and a Draft Constitutional Declaration legally defining a planned 39-month phase of transitional state institutions and procedures to return Sudan to a civilian democracy.
