Antiterrorism police units in Istanbul on Tuesday raided dozens of residences, including several college dormitories, in a crackdown on those who participated in widespread antigovernment demonstrations in June, detaining at least 30 people. http://www.nytimes.com/2013/07/17/world/europe/turkish-crackdown-on-demonstrators.html The police, citing terrorism laws, issued a temporary order withholding legal assistance to the detainees and denying them access to their families. Under those laws, the police can refuse to disclose the identities and ages of the detainees, as well as the charges against them.

“If you are a government opponent, and do things differently than dictated, you are no longer safe in Turkey.”

Eleven other people who took part in the demonstrations were arrested in the western city of Izmir on Tuesday and charged with belonging to several leftist terror organizations.

Across Turkey, dozens of people, mostly youths, were detained in recent weeks after the a small protest against Prime Minister Recep Tayyip Erdogan’s plans to raze an Istanbul park and became a broader uprising against what many called his autocratic tendencies. Riot police officers responded with tear gas and water cannons; five people died, 11 were blinded by tear gas canisters and 8,000 sustained other injuries.

Ismail Cem Bakir, 23, a computer engineering student at Istanbul Technical University, was arrested early Tuesday morning. “Plainclothes policemen, one wearing a black snow mask and filming the raid, appeared at our doorstep at 5.30 and showed us an arrest and search warrant,”

The police confiscated computers, books and magazines and threatened to charge Mr. Bakir’s lawyer, who had come over to assist the family, after he asked the masked police officer to remove his mask for transparency’s sake.
