Israel says it has rescued four hostages who were kidnapped in a Hamas-led attack on Oct. 7.  It is the largest such hostage recovery operation since the war with Hamas began in Gaza. The army said it rescued Noa Argamani, 25; Almog Meir Jan, 21; Andrey Kozlov, 27; and Shlomi Ziv, 40, in a complex special daytime operation in Nuseirat. (Hostages Families Forum Headquarters via AP)
