Medical sources in Sudan said that four people were killed in an explosion at a sports club, and several others were wounded in shootings and operations in the club.
The explosion occurred late on Saturday evening in a crowded sports club in Port Sudan.
It was not immediately clear who was behind the blast, which was also accompanied by an armed attack.
The Central Committee of Sudan Doctors indicated, “There was another attempt to target a hotel in the city, but it failed,” without going into details.
Tensions have risen in recent weeks in Port Sudan with reports that anti-government protesters have blocked roads amid growing insecurity.
The Doctors’ Committee, an independent union, blamed “tribal strife” for Saturday’s incident and urged security forces to intervene.
