Protesters rally against army violence in Azerbaijan BAKU, Azerbaijan, March 10 (UPI) -- Baku police broke up an unsanctioned protest against violence in the army by firing water cannons and rubber bullets on Sunday. More than 50 people were detained at the rally, RIA Novosti said, which was organized via Facebook. The rally comes after the death of soldiers who were allegedly killed in accidents, RIA Novosti said. About 20,000 people had signed up online to take part of the protest, but the actual attendance rates were not known. The rally is the second attempt to hold a demonstration against army hazing and deaths in Baku. The protests were motivated by the death of a 19-year-old private in January, RIA Novosti said. The teen's family said he was subject to violence, but military officials have maintained that the man died of a heart attack.
