Russia and Ukraine are holding large military exercises along their shared border as the Ukrainian military claims to be closing in on rebel strongholds in Donetsk and Luhansk, NPR's Karoun Demirjian reports from Moscow.

There are also 192 Russian warplanes and 137 military helicopters, as well as artillery systems and multiple rocket launchers, he said.
" 'All this is aimed at keeping the Ukrainian military on its toes,' Timothy Ash, an emerging-markets economist at Standard Bank Group Plc in London, said in an e-mail.

Russia, meanwhile, took a number of measures on Tuesday, according to Reuters,
