Turkish media is reporting today that Prime Minister Erdogan spoke to President Ahmadinejad on the phone today to discuss the worsening situation in Syria. Turkey has arrived at critical crossroads with Syria after months of dialogue with Assad apparently have not produced any results, and the Turkish government is expected to eventually withdraw its support from his regime. Such move leaves Iran as the only regional power still supporting the Syrian government. But there are signs that the Iranian support is also evaporating. This week, Tehran replaced its ambassador to Damascus who had close ties to Assad and other members of the ruling family in the country.
