According to a medical source at a hospital in Shendi city in River Nile state, a landmine killed ten people on a bus in northern Sudan on Saturday.

The conflict pitting the regular army against the paramilitary Rapid Support Forces (RSF) erupted in April and has led to thousands of people being killed and millions displaced.

The source told AFP that "10 civilians were killed as a result of a mine explosion on a bus".

The source said that the vehicle was transporting the passengers from eastern Al-Jazira state to Shendi, 180 kilometers (112 miles) from Khartoum, when the blast happened.

It is believed to be the first landmine blast to have occurred during the war between Sudan's rival generals, army chief Abdel Fattah al-Burhan, and his former deputy, Mohamed Hamdan Daglo.

Neither side has officially commented on the explosion.

War crimes involving the random shelling of residential areas, the use of torture, and the arbitrary arrest of civilians have been leveled against both sides.

The RSF has also been charged with widespread looting, rapes, and mass executions driven by racial hatred.

The RSF took over more land in the country's east, where the army is still in charge, after months of a virtual standoff between the two armies.

The capital's streets and almost the entire western area of Darfur are under the grip of the dreaded paramilitary, which has also advanced east, north, and south.

More than 13,000 people have been killed since the war began, according to a conservative estimate by the Armed Conflict Location & Event Data Project, and the United Nations says more than seven million people have been displaced.
