A wave of drone strikes by Sudan’s paramilitary Rapid Support Forces (RSF) hit Port Sudan on Tuesday, igniting fuel depots and damaging key infrastructure including the port, airport, and a major power substation, according to Reuters.

The RSF, a former militia turned powerful military faction, has intensified attacks on the city previously a government and aid hub marking a sharp escalation in the civil war.

The strikes have interrupted relief operations and power supplies, exacerbating what the UN describes as the world's worst humanitarian disaster, Reuters reported.

Port Sudan, once considered a safe zone, is now on high military alert as turmoil moves eastward.
