Azerbaijan has launched “anti-terrorist operations” in Nagorno-Karabakh, sparking fears of a full-scale war with Armenia over the disputed region.
Baku’s defence ministry said it was using “high-precision weapons” to target Armenian forces.
There are reports that Stepanakert, the region’s de-facto capital, is under artillery bombardment.
Earlier on Tuesday, four Azerbaijani police officers and two civilians were killed in mine blasts in the breakaway region, with authorities blaming Armenian separatists for the deaths.
