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.

Muhammad Sinwar, one of the remaining top leaders of Hamas in Gaza, was reportedly targeted by Israel in a massive airstrike at a hospital in the southern Gaza Strip on Tuesday afternoon.

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.
