Israel said it killed a senior Hamas commander on Saturday in a strike on a vehicle inside Gaza.
In a statement, the Israeli military said it had "struck a key Hamas terrorist" in Gaza City.
The Hamas-run Civil Defence spokesman, Mahmoud Basal, told the BBC that four people were killed in the strike. He said multiple passers-by were also injured by the blast.
Local sources said the strike may have targeted Raed Saad, a senior commander in Hamas's armed wing, the Qassam Brigades.
The BBC is prevented by Israel from reporting independently from inside Gaza and is unable to verify details of the incident.
