 A top U.N. envoy in Iraq said Friday more than 50 mass graves have been found in Iraq territory that was once held by the Islamic State.
Jan Kubis told the U.N. Security Council that three of the 50 graves were found on April 19 in the soccer grounds area of Ramadi. Kubis said that ISIS "remains a formidable and determined enemy that constantly adjusts its tactics and attack patterns,†and used the discovery as an example.
The most recently discovered graves found in Ramadi in April might contain the remains of up to 40 people. He called on the international community to “take steps to ensure the accountability†of Islamic State extremists.
