Hamas says it will release American Israeli Edan Alexander and the bodies of four other hostages only if Israel implements their cease-fire agreement.

A senior Hamas official said talks over the ceasefire's second phase would need to begin the day of the release and last no longer than 50 days. Israel would also need to stop barring the entry of humanitarian aid.

IDF says it targeted mid-level Hamas commanders and is prepared to widen offensive beyond airstrikes; death toll reportedly over 230; White House back offensive, says it was consulted beforehand
