A second person has died from his injuries after being hit by a grenade explosion during clashes between police and protesters yesterday,
"Another of our citizens who was seriously wounded has lost his life. We have lost a person who was wounded by a hand grenade. The death toll has risen to two," Istanbul governor Huseyin Avni Mutlu told reporters.
The other victim was a 30-year-old man who was shot in the head during Thursday's protests.
Riots erupted on Thursday after police fired live ammunition at crowds who were commemorating the death of a young man in the occupy Gezi protests last year.
There has also been unrest following the recent deaths of hundreds of miners.
