Ukraine's military said on Tuesday pro-Russian rebels were amassing heavy weapons in depots around separatist-held Donetsk city despite a ceasefire deal.

Rockets killed more than 10 civilians and soldiers deep in Ukrainian government-held territory on Tuesday and rebels pushed on with an assault on an army-held rail junction, setbacks that showed Kiev's position worsening on the eve of peace talks.

Ukraine plans a "Day of Silence" on Tuesday to try to rebuild a ceasefire with pro-Russian separatists that has all but disintegrated, but accompanying peace talks -- the first in three months -- look likely to be delayed.
