Trump confirmed the US military had defeated the top candidate to replace supreme leader IS Abu Bakr al-Baghdadi after his death.

"This person is very likely to take the position of leader, but is now dead," US President Donald Trump today wrote on Twitter, referring to a member of the Islamic State militant group (IS) ) claiming to be destroyed.

The White House boss did not reveal his identity or details on how to kill this man. However, Washington said yesterday that Abu Hassan al-Muhajir, an IS spokesman, as well as Baghdadi's "right hand", was also removed.

Trump on October 27 declared Baghdadi, the supreme leader of the Islamic State, died by detonating a suicide bomb belt when a US special task force was brought to an end during a raid in Idlib, northwestern Syria on October 26. . The rebel group has not confirmed this information, nor mentioned the potential successor of Baghdadi.

Baghdadi, thought to be about 47 to 49 years old, was born in Iraq and became the supreme leader of IS in 2010, leading the group to occupy vast territories in Iraq and Syria. Experts say IS could hardly find a replacement for Baghdadi because of his enormous influence on the members of the group.

Muhajir's death is thought to make this even more difficult. Terrorists say their leader needs certain characteristics, such as coming from the Quraysh tribe of the Prophet Mohammed and mastering the knowledge of Islamic law.
