Exclusive footage by China Media Group shows the extensive damage suffered by Gandhi Hospital in Tehran after US-Israel strikes on Sunday.

Large sections of the building's exterior were torn away, windows shattered and debris from the blast scattered across the ground.

Iranian Ministry of Foreign Affairs spokesman Esmaeil Baghaei said on Monday that the two countries "continue to indiscriminately strike residential areas, sparing neither hospitals, schools, Red Crescent facilities, nor cultural monuments."

At least 555 people have been killed in the US-Israel strikes against Iran since Saturday morning, the Iranian Red Crescent Society (IRCS) said on Monday. In a statement published on its official website, the IRCS noted that 131 Iranian counties were targeted in the strikes.
