US President Donald Trump's administration says the Islamic State of Iraq and Levant (ISIL, also known as ISIS) group remains the biggest threat to religious freedom around the world.

The US Department of State says the murders of Yazidis, Christians and Shia Muslims at the hands of ISIL amounted to genocide.

The annual report says almost 80 percent of the world's population continues to live under threats limiting freedom to worship.

The countries criticised include US allies Saudi Arabia and Bahrain.
