Israeli analysts think it was likely that Mr. al-Haddad was killed inside the building, the officials said.Accounts of how many were killed and wounded in the attack differed as of Friday evening.Dr. Mohammed Abu Salmiya, the director of al-Shifa hospital in Gaza, said in a text message that at least seven people were killed in the strikes on Gaza City, and 10 others were wounded. Mahmoud Basl, a spokesman for Gaza’s Civil Defense emergency service, said by phone that five people had been killed in the strikes.ImageIsraeli military launched strikes on an apartment building in central Gaza on Friday.Credit...Saher Alghorra for The New York TimesThank you for your patience while we verify access.
