Kremlin says accords underpinning Ukraine truce must be 'unconditionally observed'

MOSCOW (Reuters) - The package of measures underpinning a ceasefire in eastern Ukraine must be "unconditionally observed", Russian President Vladimir Putin's spokesman said on Sunday.

Dmitry Peskov was commenting on a remark by a senior pro-Russian separatist commander that, despite the truce deal that took effect at midnight, rebels have the right to fire on the town of Debaltseve in east Ukraine as it is "our territory."
