"We're seeing reports that some users are not able to access YouTube in Turkey. There is no technical issue on our side and we're looking into the situation," a Google Inc spokesperson said in an emailed statement. Meanwhile, Turkish Prime Minister Tayyip Erdogan said the posting on YouTube of a recording purportedly of top officials discussing possible military operations in Syria was "villainous". "They even leaked a national security meeting. This is villainous, this is dishonesty (...) Who are you serving by doing audio surveillance of such an important meeting?" Erdogan told a crowd of supporters in Diyarbakir. Turkey blocked YouTube as a precaution after voice recordings purportedly of senior officials discussing a potential military operation in Syria created "a national security issue", a source at the prime minister's office said on Thursday.
