Sudan’s opposing sides have accused each other of violating the latest ceasefire, which was negotiated by the US and Saudi Arabia and is now in its third day. Witnesses reported clashes between rival factions on Thursday in Khartoum, Omdurman, and El Obeid. The ceasefire was reached after five weeks of fighting in Khartoum and other parts of Sudan, including the volatile western region of Darfur. The fighting centres on a power struggle between Sudan’s army and the paramilitary Rapid Support Forces (RSF), which has worsened a humanitarian crisis, forced over one million people to flee, and threatened to destabilise the region. The RSF has blamed the army for ceasefire breaches, while the army has accused the RSF of violating the truce. The US Department of State has warned that Russia’s Wagner mercenary group has been supplying the RSF with surface-to-air missiles to fight Sudan’s army.
