Turkish Prime Minister Tayyip Erdogan gestures as he speaks to supporters during his visit in Cologne May 24, 2014.
Turkey's embattled prime minister lashed out at international media on Tuesday, accusing news outlets of stirring unrest during the one-year anniversary of mass anti-government protests.
Recep Tayyip Erdogan singled out CNN International, whose reporter was arrested live on air last Saturday while covering street clashes, accusing the network of spying.
"International media organisations who came to Istanbul for provocative and exaggerated broadcasts were left empty-handed," Erdogan told members of his ruling AKP party in an apparent reference to the incident.
On Saturday, police violently dispersed demonstrators in Istanbul and Ankara as they marked a year since the start of nationwide protests denouncing Erdogan's authoritarian rule.
Riot police fired tear gas and water cannon at protesters on Istanbul's side streets to prevent them reaching the city's iconic Taksim Square, the epicentre of last year's uprising.
News outlets were also targeted, with Turkish police briefly detaining a CNN team in the middle of a live broadcast from the square.
"Turkish police released CNN team after half an hour. Officer apologised for another officer who kneed me while I was being detained," CNN's Ivan Watson said on Twitter.
On Tuesday, Erdogan called Watson a "lackey" who had been "caught red-handed" trying to bring chaos to Turkey.
"[CNN] doesn't care about a free, impartial and independent press. They are assigned to work like spies," Erdogan said.
Last year's wave of protests was sparked by government plans to uproot trees at Istanbul's central Gezi Park and erect a shopping mall on the site.
At least eight people were killed and thousands were left injured during three weeks of unrest that followed.
Erdogan has branded demonstrators "extremists" and "looters" and accuses them of seeking to derail his government's economic achievements over the last decade.
