Two men died and about 10 others were injured in Istanbul during violent clashes between police and protesters on Thursday, officials said, in the latest eruption of anger against the Turkish government.
"Unfortunately we have not been able to save Ugur Kurt," Istanbul governor Huseyin Avni Mutlu wrote on Twitter, several hours after the 30-year-old was brought to hospital with a gunshot wound to the head, AFP reported.
A second person died from his injuries on Friday after being hit by a grenade explosion during clashes between police and protesters the day before, Istanbul governor Huseyin Avni Mutlu said.
Violence erupted when police fired live ammunition as well as tear gas and rubber bullets to disperse protesters who denounced the death of a teenage boy who fell into a coma during anti-government unrest last year.
The demonstrators, also protesting over last week's mine disaster in the western Turkish town of Soma, responded by hurling stones and Molotov cocktails at police and setting fire to an armored police vehicle.
Erdogan visit brings divisions to streets of Cologne
Meanwhile, a visit by Erdogan to Cologne on Saturday to address thousands of expatriate Turks threatens to bring Turkey's political tensions to German streets, despite an appeal by Chancellor Angela Merkel for him to adopt a sensitive tone.
Erdogan typically addresses a mass audience of expatriate Turks when visiting Germany. They are rousing patriotic affairs with thousands waving the Turkish flag. In 2008 he caused uproar by warning Germany's largest minority against assimilation, Reuters reported.
At least 16,000 supporters are expected at the 10th anniversary of the Union of European Turkish Democrats (UETD).
As many as 30,000 anti-Erdogan protesters are due to gather nearby on Saturday, as well as a German far-right party, leading Yeni Safak, a pro-Erdogan paper in Turkey to warn on its front page on Friday of a "trap". Berlin, it suggested, wanted to hold Erdogan responsible for stirring trouble.
Critics in Germany say it is insensitive to give such a speech 11 days after Turkey suffered its worst ever mining accident, in which 301 miners died.
