A hardline Sri Lankan monk who is a close ally of ousted former president Gotabaya Rajapaksa, has been sentenced to nine months in prison for insulting Islam and inciting religious hatred.

Galagodaatte Gnanasara was convicted on Thursday for the remarks, which date back to 2016.

Sri Lanka rarely convicts Buddhist monks, but this marks the second time that Gnanasara, who has repeatedly been accused of hate crimes and anti-Muslim violence, has been jailed.
