Israel says it has begun sending troops into Gaza as part of a larger ground operation aimed at pushing Hamas to demilitarize and release the remaining hostages it holds.

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,

Muhammad Sinwar was born in Khan Younis in 1975. He is the younger brother of Yahya Sinwar, who masterminded the Hamas-led attacks on Israel that started the war in Gaza in October 2023 and in whose footsteps Muhammad Sinwar followed for much of his life.
