We don't know if this is true, but the claim sheds some light on Russia's motivation (or at least justification) for its intervention in Syria. The Long War Journal reports Oct. 3, citing social media postings, that a small group of Crimean Tatars and other militants from the Russian-annexed peninsula, calling themselves the Crimean Jamaat, has pledged bayah (allegiance) to the Nusra Front, al-Qaeda's Syrian franchise. The pledge was apparently announced by Nusra sympathizers on Twitter, and on the official social media site of Nusra's Sayfullah Shishani Brigade, which is largely comprised of Chechens. "Kataib Crimean Tartars under the leadership of Emir Ramadan al Krim [Crimean] pledged allegiance to al Qaeda in Sham and joined the Al Nusrah Front," read a statement on White Minaret, the Sayfullah Shishani site. The page is said to also include pictures of the group, reportedly based in Hama governorate.

A large section of the Aral Sea has completely dried up for the first time in modern history, according to NASA. Images from the US space agency's Terra satellite released last week show that the eastern basin of the Central Asian inland sea—once the fourth largest in the world—was totally parched in August. Images taken in 2000 show an extensive body of water covering the same area. "This is the first time the eastern basin has completely dried in modern times," Philip Micklin, a geographer emeritus from Western Michigan University told NASA's Earth Obsrvatory. "And it is likely the first time it has completely dried in 600 years, since medieval desiccation associated with diversion of Amu Darya to the Caspian Sea."

Tajikistan sealed its border with Afghanistan this week, after clashes with armed rebels left 48 dead. Security forces are now searching for Tolib Ayombekov, a former rebel who became a commander of the border guard after a 1997 peace deal and is now believed to have taken up arms again. Ayombekov has been a fugitive since he refused to show up for questioning about the July 21 murder of a local security official in southern Badakhshan province, or to turn over men under his command suspected in the slaying. A conflict over control of the cross-border traffic in Afghan opium is said to be behind the fighting.
