President Bashar Assad of Syria is facing increasing pressure now that Jordan's King Abdullah II voiced his desire to see Assad's regime to step down for the good of the country. King Abdullah was the first Arab leader to make such a call but he did so amid increasing violence within the country between anti-government protesters and soldiers still loyal to Assad. Dr. Zaher Sahloul  has seen the Assad's violent methods of tamping down civilian protest first hand.   Sahloul is president of the Syrian American Medical Society, where he has been working to send physicians and financial aid to thousands of Syrian refugees along the Turkish border. Jonathan Head, BBC correspondent in Istanbul, reports on the latest developments.
