The 20-year-old died of a bullet wound in the town of Yuksekova in Hakkari province, which borders Iran and Iraq, after clashes erupted Sunday when a crowd of demonstrators defied an official ban on a planned gathering to mark Newroz, or the Kurdish New Year, they said.

A 35-year-old man, identified as Zeki Erinc, died earlier in a hospital in the eastern city of Van, where he had been taken with a bullet wound Saturday, according to doctors there.

An official from the Van governor's office confirmed the death, but was unable to provide details on the nature of his injuries.

Around 50 people, among them policemen, were wounded and some 130 others were detained in Saturday's clashes in Van, according to the police.

The unrest in Van and other cities in the southeast erupted when gatherings meant to mark Newroz degenerated into demonstrations in support of the armed separatist Kurdistan Workers' Party (PKK), listed as a terrorist group by Ankara.

Newroz is a traditional platform for Turkey's Kurds to demonstrate support for the PKK and demand broader rights. About 50 people were killed during Newroz clashes in 1992.

The PKK took up arms for self-rule in Kurdish-majority southeast Turkey in 1984, sparking a conflict that has claimed more than 37,000 lives.
