The strike hit an underground site in Khan Younis, according to Israel’s military, and an official said it could take days for Israel to determine whether the strike was successful.

Israel has targeted Hamas leader Mohammed Sinwar in a strike on a hospital in southern Gaza on Tuesday evening, according to a senior Israeli official and two sources familiar with the matter.

The Israeli military refused to comment on the strikes, but had warned residents of Jabaliya to evacuate late Tuesday night due to Hamas infrastructure in the area, including rocket launchers.
