Azerbaijan has announced a "unilateral ceasefire" in fighting with Armenian forces over the disputed Nagorno-Karabakh region.
A defence ministry spokesman said the Azeris were acting in response to international calls to halt violence.
But the Armenia-backed Karabakh forces said this was false and Azerbaijan was continuing to fire shells.
Nagorno-Karabakh has been in the hands of ethnic-Armenian separatists since a war that ended in 1994.
Fighting had continued into Sunday, after clashes left 30 soldiers dead and caused civilian casualties.
