Binyamin Rofshitz, an 82-year-old man who was in the apartment in Haifa's Neveh Sha'anan neighborhood in which a gas canister exploded on Thursday morning, injuring 26 people and severely damaging the building, died on Sunday in Haifa's Rambam Hospital.
Police submitted a request to carry out an autopsy and were continuing to investigate the explosion.
Eight families, whose apartments were destroyed by the blast, were granted temporary housing in the nearby Beit Abba Hushi community center.
Residents said there had been strong gas odors over the few days leading up to the incident. However, no one made an official complaint to the gas company.
