A grenade exploded during a wedding party in Sudans capital Monday, killing at least seven people, including three children, security and medical officials said. The officials said the explosion also injured at least two dozen adults and children, who were taken to nearby hospitals from the party in the Shegla neighborhood in Khartoums al-Haj Youssef district. The officials spoke on condition of anonymity because they were not authorized to brief the media. Images shared online showed injured people with bandages and blood on their bodies being treated at a hospital. A fight between two people at the party escalated into one of them throwing the grenade and causing the explosion, the health ministry said in a statement, according to The Associated Press. While such explosions are rare in Khartoum, the city has suffered from insecurity in recent months. Police found at least three people slain in unclear circumstances in different parts of the capital over the past two weeks.
