The Syrian president - Bashar al-Assad - has cast his vote in a controversial presidential election, which he is widely expected to win.
The balloting, Syria's first multi-candidate election in more than 40 years, comes as a devastating, three-year civil war that activists say has killed more than 160,000 people, about a third of them civilians, rages on.
The opposition and government critics have condemned the vote as a sham. Syria's two main internal opposition groups are boycotting the vote while many activists around the country refer to it as "blood elections".
Syria will hold a presidential election on 3rd June, state media reported, setting the date for a vote likely to give President Bashar al-Assad a third term.

In an interview with BBC News, Ukip leader Nigel Farage said it was "more than likely" that it was Syrian rebels, not pro-Assad forces, responsible for chemical attacks in the country.
Asked about comments he made recently in support of Russian president Vladimir Putin, Mr Farage said:
We were about to go to war in Syria because poison gas - sarin gas - had been used, and everybody in London and Washington and Brussels assumed it had been used by Assad.
And Putin said, 'Hang on a second, don't be so sure.'
It turns out it's more than likely it was the rebels that used the gas.
If Putin hadn't intervened, we would now be at war in Syria.
