Marwan Issa, the deputy commander of Hamas’s military wing, was killed in an Israeli strike this month in central Gaza, U.S. national security adviser Jake Sullivan confirmed Monday. Earlier Monday, Israel’s military said it was carrying out a “precise operation” at Gaza’s al-Shifa Hospital, citing Israeli intelligence that the complex was being used by senior Hamas militants. The Gaza Health Ministry said communications were cut and reported people killed or injured. The Washington Post could not immediately verify either side’s claims.
