By Daren Butler and Humeyra Pamuk ISTANBUL (Reuters) - Turkey's president on Friday ruled out any ban on Facebook and YouTube after Prime Minister Tayyip Erdogan said the sites could be shut to stop his foes anonymously posting audio recordings purportedly exposing corruption in his inner circle.

Gross, who oversaw more than $1.91 trillion in assets as of the end of last year and who is known on Wall Street as the 'Bond King', said in a phone call to Reuters last Friday: "I'm so sick of Mohamed trying to undermine me." When asked if Reuters could see the evidence about El-Erian and the allegation he was involved in the article, Gross said: "You're on his side.
