A mass grave was discovered at al-Shifa Medical Complex after a deadly Israeli assault last month left the Gaza City hospital in ruins.

Several bodies were found Monday in the hospital's courtyard, including at least one person wearing underwear who appeared to have been "executed recently".

After Israeli forces withdrew from the hospital on 1 April, teams from several government ministries were deployed to al-Shifa to remove and identify bodies, the Middle East Eye reported. 

The searches were initiated after survivors said they witnessed the summary execution of Palestinians by Israeli forces during the two-week raid that started in mid-March.
