U.S. Ambassador to Ukraine Geoffrey Pyatt has expressed concern about renewed violence during protests in central Kyiv on Tuesday, Interfax-Ukraine reports.

"After weekend progress in Kyiv, sorry to see renewed violence. Politics needs to happen in the Rada, not on the street," he wrote to his Twitter account on Tuesday.

To recall, severe clashes continue near the Verkhovna Rada in central Kyiv. On Shovkovychna Steet protesters have burnt a truck, tires are in fire on Hrushevskoho Street, in Mariyinsky Park firecrackers are being thrown towards police. 

Meanwhile, one of the oposition leaders Oleh Tyagnybok announced a general mobilization.

The Svoboda All-Ukrainian union wrote this on Twitter.

“Oleh Tyagnybok calls all men to arrive in Kyiv immediately - general mobilization!”, - it is said in the message.
