Hello and welcome to NewsHour from the BBC World Service.
Coming to you live from London, I'm Gary O'Donoghue.
Coming up on the programme, how one Russian woman lured men from Syria,
Egypt and Yemen to fight in Ukraine.
First, though, we turn to Iran,
where officials say around 2,000 people, including members of the security forces,
have been killed in successive nights of anti-government protests,
which it says have now been brought under full control.
Internet traffic is intermittent,
though some people have managed to use telephones to communicate with people inside the country.
It appears that the protests may have slowed somewhat,
though firm information is still hard to come by.
Nevertheless,
President Trump has urged Iranians to keep on protesting and declared that help is on its way.
