By Orhan Coskun ANKARA (Reuters) – Prime Minister Tayyip Erdogan applied to Turkeys constitutional court on Friday to challenge the alleged violation of his and his familys rights by social media, a senior official in his office told Reuters. Erdogans government blocked Twitter and YouTube in March, drawing international condemnation, after audio recordings, purportedly showing corruption in his inner circle, were leaked on their sites. The Twitter block was lifted earlier this month after the constitutional court ruled that it breached freedom of expression, a decision Erdogan has since said was wrong and should be overturned. YouTube remains blocked in Turkey.
