Sudan fighting: What we know so far

If you're just joining us, here's a recap of what we know about the situation in Sudan:

• Widespread fighting has erupted in the Sudanese capital, Khartoum, between two factions of the military
• There has been heavy gunfire and explosions in Khartoum and several other towns involving army units and the Rapid Support Forces (RSF) - a powerful, paramilitary group
• At least three civilians have been killed in today's clashes, a doctors' trade union says
• RSF claims to be in control of several key sites, including the Republican Palace - the seat of the country's presidency - as well as Khartoum International Airport
• Airlines have halted flights to Sudan and there have been reports that two people were killed when a shell hit a passenger plane
• RSF commander Mohamed Hamdan Dagalo says his troops will keep on fighting until all army bases are captured
• The army says airstrikes have destroyed at least two RSF bases
• A BBC correspondent in Khartoum has been beaten up by a Sudanese soldier while on the way to his workplace

• Tensions have increased between the government and the paramilitary group in recent days
• It comes after Sudanese groups and the ruling military junta failed to reach an agreement last week over transitioning to a civilian-led government, with one of the key issues holding up the deal being the integration of the RSF with the army

  More on civilian deaths

  We have got a bit more information about the civilian deaths in Khartoum we reported earlier.

  The doctors' union which reported the deaths said three civilians had been killed at Khartoum Airport and in the neighbouring North Kordofan state.

  In a statement on Facebook it added that at least nine other people were wounded in the clashes.

  The statement did not specify how the two people died at the airport, which was the scene of earlier fighting as the regular army and paramilitaries battled for control, the AP news agency reports.
