Blast at hospital from 'rocket aimed at Haifa' - Regev
More from Mark Regev, the senior adviser to the Israeli Prime Minister, who has told BBC News it is the belief of the Israeli authorities that a Hamas rocket was to blame for the blast at the Al Ahli hospital.
"We know that at the time of this tragedy in Gaza, there was a huge barrage against targets in central Israel. We had the siren here in Tel Aviv, and I went to a bomb shelter," he said.
"We know they fired rockets at that same time. Hamas put out a statement that they were sending a long-range rocket on Haifa [northern Israel] at this time."
"Now no rocket actually reached Haifa. Where did that rocket go? Where did it land?"
The BBC is working to verify what caused the blast at the Al Ahli hospital, which Hamas authorities have blamed on the Israeli military.
