The Syrian Observatory for Human Rights says it received "information confirming" the death of Islamic State leader Abu Bakr al-Baghdadi.
Rami Abdel Rahman, head of the Britain-based Observatory, said al-Baghdadi has died in Deir al-Zour province in eastern Syria. He could not provide any more details on when or how al-Baghdadi was killed.
The Observatory's statement comes one month after it disputed Russia's claim that it could have killed al-Baghdadi in an airstrike around the city of al-Raqqa on May 28.
Telegram channels allegedly affiliated with the militant group have not issued any statements yet.
