DUBAI (Reuters) - British maritime security firm Ambrey reported on Tuesday that the paramilitary Rapid Support Forces (RSF) had launched a drone attack on facilities at Port Sudan, targeting the container terminal and escalating a two-year-long conflict.

PORT SUDAN — Sudan's army-aligned government on Tuesday severed diplomatic ties with the United Arab Emirates, accusing the Gulf state of supplying weapons used by the rival paramilitaries to strike its de facto capital.

Sudan's paramilitary Rapid Support Forces launched a second drone strike in as many days on Port Sudan, targeting fuel depots in the eastern city early on Monday, security sources told Reuters, in a major escalation of a two-year-long conflict.
