The Israel Defense Forces targeted the head of Hamas' military wing, Mohammed Sinwar, in an airstrike on a bunker underneath a hospital in Khan Younis, three Israeli officials told Axios. Why it matters: The death of Sinwar,

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.

At least six people were killed and 40 wounded, according to the Hamas-run Gaza Ministry of Health, which did not name Muhammad Sinwar as one of the dead.

This Israeli prime minister's comments are likely to complicate talks on a new ceasefire that seemed to gain momentum after Hamas released the last living American hostage this week.

Israeli officials said the military had launched an attack targeting Mohammad Sinwar, one of Hamas’s top remaining commanders in Gaza and the brother of a leader killed last year.
