The Palestine Red Crescent Society (PRCS) has accused Israeli forces of attacking its headquarters in Gaza, killing one worker and injuring three others.
The humanitarian organisation said the attack "sparked a fire in the building" in the early hours of Sunday morning.
Describing the overnight attack on the facility in the southern city of Khan Younis as "deliberate", the Red Crescent said its HQ's location is "well known" to the Israeli military and is "clearly marked with the protective red emblem".
The Israel Defense Forces (IDF) said it had "no knowledge about neither artillery nor any air strikes" when asked by the BBC about the accusation.
A video shared by the Red Crescent on social media showed parts of the building on fire and filled with clouds of smoke, while aftermath pictures showed heavy damage to the building and several large bloodstains.
