Protests have marked the fourth day in several Turkish cities, after the funeral of a 22-year-old protester whose murder has re-ignited anti-government anger in Turkey.

Clashes erupted in the early hours of Thursday in areas of Ankara and Istanbul, with injuries reported in both cities. Police detained scores of protesters in Istanbul.

In the southern city of Hatay, a group of about 200 people confronted with the police who then responded with tear gas and water cannon.

The death of 22-year-old Ahmet Atakan in Hatay on Sunday has renewed a protest movement that had cooled after thousands took to the streets in June in an expression of discontent against Prime Minister Recep Tayyip Erdogan's government.

The cause of Atakan's death is in dispute. Witnesses say he was hit on the head by police, while police say he fell from a rooftop.

Muammer Guler, the interior minister, said on Wednesday that protestors were attempting to use the death to "spread chaos".

"Images were broadcast on television showing that police were not in the process of intervening... and that he fell from a height," Guler said in Ankara.
