At least one Palestinian has been killed and 16 others injured in an explosion at a house owned by a Hamas member in the Gaza Strip, medics and witnesses said.
Muawiya Hassanein, the head of Gaza emergency services, confirmed the incident on Saturday in Gaza City, saying health workers had not yet identified the person who died.
Witnesses said the house belonged to Nadir Abu Shaaban, a member of the Hamas movement which has ruled Gaza for nearly a year.
The cause of the explosion is not yet known.
Hamas security forces have begun an investigation into the incident.
Several Gazans have been killed and wounded in recent years by accidental explosions while constructing or handling homemade rockets and other weapons in the territory.
