Israeli army spokesperson Daniel Hagari says its troops has rescued four Israeli hostages alive from Gaza after a "complex mission".
Over 250 were taken on October 7, after Hamas's unprecedented attack in Israel resulting in the deaths of 1,194 people, according to an AFP tally based on Israeli official figures.
Israel's retaliatory military offensive has killed at least 36,600 people in Gaza, according to the Hamas-run territory's health ministry.
