Aid groups in Sudan say a military airstrike hit a local market in the country’s western region, igniting a huge fire and killing at least 54 people.

Sudan’s military has consolidated its grip on Khartoum, retaking more key government buildings a day after it gained control of the capital's Republican Palace from a notorious paramilitary group.

Sudan's miliary says it has broken a paramilitary group's yearlong siege of the crucial city of Obeid, restoring access to a strategic area in the south-central region and strengthening crucial supply routes in their nearly two years of war.
