Trump to address 'crisis of Islamist extremism', but 'not here to lecture'

"This is not a battle between different faiths, different sects, or different civilizations," but "a battle between good and evil".

US president Donald Trump will tell Muslim leaders that stamping out terror threats will require "honestly confronting the crisis of Islamist extremism and the Islamist terror groups it inspires".

In excerpts released by the White House ahead of his speech on Sunday, Mr Trump will call for unity across the Muslim world in the fight against terrorism.
