Day of Fasting and Prayer for Syria

I am very sad about what is happening in Syria.  The Pope, who runs a church I do not belong to, has very sensibly suggested a day of Prayer and Fasting on September 7th.  I don't know what he intended to mean by fasting, but since Syria is a predominantly Muslim country, I am going to try and abstain from food and water from sunrise to sunset.  I have nothing big to do that day, so it should be possible.  I encourage anyone who reads this to do whatever seems right to you.
