Nagorno-Karabakh: Armenia and Azerbaijan accuse each other of breaking fresh truce

Casualties reported after Armenia says it was shelled twice, while Azerbaijan says mortars and artillery were used against it

Armenia and Azerbaijan accused each other on Sunday of violating a new humanitarian ceasefire in fighting over the mountain enclave of Nagorno-Karabakh, hours after it was agreed.

The truce reached on Saturday came into force at midnight after a week-old Russian-brokered ceasefire failed to halt what has been the worst fighting in the South Caucasus since the 1990s.
