Nagorno-Karabakh conflict: Armenia and Azerbaijan exchange claims of new attacks

Azerbaijan accused Armenia on Wednesday of trying to attack its gas and oil pipelines and warned of a "severe" response as tensions rose sharply around a fraying ceasefire in the mountain enclave of Nagorno-Karabakh. Armenia hit back by saying Azeri forces wanted to seize control of the tiny territory in the South Caucasus, which is governed by ethnic Armenians, and accused Azerbaijan and its ally Turkey of "aggression" despite Saturday's ceasefire deal.
