Gunmen open fire at Moscow concert hall, killing dozens

The Kremlin says that more than 40 people have died and more than 100 were wounded in a Friday night attack. The motive for the shootings or who may be responsible is not known. And, for more than a decade, Hosam Bahgat has been under criminal investigation for his work with the Egyptian Initiative for Personal Rights, a human rights group. The court's investigation concluded this week and the charges against Bahgat were dropped. Also, Mongolia’s nomadic herders are facing a savage dzud winter, after more than 2 million livestock have frozen to death. Scientists say this lethal phenomenon — extreme cold and heavy snow following a summer drought — is occurring more frequently and is linked to climate change. Plus, on World Water Day, we hear how a farm in Iraq was hit by water shortages.
