The news is abuzz with the reported use of chemical weapons in Syria.  However, no one seems to be able to tell if there was in fact chemical weapons used or who used them.  The President Bashir Asad-led Syrian Arab Republic (SAR) blames the rebel forces meanwhile the Free Syrian Army and the newly formed government of the National Coalition for Syrian Revolutionary and Opposition Forces (Syrian National Coalition/SNC) blame the SAR.

**Something that I learned today was that the Friends of Syria group recognizes the SNC as the sole legitimate representative of the Syrian people.  The Friends of Syria group has 111 members.  That makes the SNC the government of Syria according to 57.5% of the 194 "universally recognized" countries of the world (United Nations members plus Vatican) or 54.7% of the 203 de facto partially countries of the world (United Nations members plus Vatican as well as Republic of China, Kosovo, Transnistria, Nagorno-Karabakh, South Ossetia, Abkhazia, Northern Cyprus, Sahrawi Arab Democratic Republic, and Palestine)**

There has not been much done in the way of mapping the alleged chemical weapons attack.  I have only been able to find two amateur made maps that make it appear that SAR launched the attack to strike at rebel held positions near Aleppo.

MiddleEast_BRK made this map showing the alleged attack being done in order to blunt a rebel assault on a military base.

Meanwhile Blind Warrior made a map claiming the attack was in the same place but targeting a rebel held police station.
