For a year now, freeing the hostages taken by Hamas has been a top goal for Israel, but some 101 remain unaccounted for and the hope of a deal to get them home is waning quickly.

Al-Shifa, Gaza's largest hospital, which once had 800 beds, weathered a nearly two-week raid in March, in what Israeli military officials at the time called one of the "single-largest operations in the war". WHO workers, who gained access to the facility in early April after the raid, called the hospital "an empty shell" of itself.
