Gunfire rattled the Sudanese capital, Khartoum, Thursday on day six of the conflict as the latest attempt at a cease-fire between rival Sudanese forces fell through. Over Wednesday night and into Thursday morning, gunfire could be heard almost constantly across Khartoum. Artillery shelling and airstrikes seemed to have eased from previous days, but residents still reported a few explosions. Sudan's paramilitary force is locked in a deadly struggle with the Sudanese army to control the strategic northeastern African country. The World Health Organization said almost 300 people have been killed in the past few days, adding that the toll could likely be higher because many bodies lie uncollected in the streets.
