Kiev on Sunday accused Russia of sending more equipment, including rocket launchers, across the border into the restive east of the country.
Over the past 24 hours "a convoy of military equipment, including three Grad rocket launchers, have crossed into the territory of Ukraine" and continued on to Nizhniy Nagolchyk, a village in southern Lugansk region, one of the areas controlled by pro-Russian rebels, security spokesman Andriy Lysenko said in a briefing.
