Kazakh President Nazarbayev treated for cold before Armenia visit

Kazakh President Nursultan Nazarbayev is being treated for a cold, his office said on Tuesday, prompting speculation that the illness was diplomatic. The announcement was unusual because the presidential office rarely provides any comments on the state of the 76-year-old leader's health, which is a state secret under Kazakh law. Armenia will host a top-level meeting of the Collective Security Treaty Organisation (CSTO), a Russia-led security bloc, on Oct. 14.
