Azerbaijan said on Sunday that Armenian forces had fired rockets at its second city of Ganja, killing one civilian and wounding four, and threatened to retaliate by destroying military targets inside Armenia.
The developments marked a sharp escalation of the war in the South Caucasus that broke out one week ago.
Until now, the main fighting has been between Azerbaijan and Nagorno-Karabakh, an ethnic Armenian enclave inside Azerbaijan, but it now threatens to spill over into a direct war with Armenia itself.
“Azerbaijan will destroy military targets directly inside Armenia from which shelling of its population centers is taking place,” presidential aide Hikmet Hajiyev said.
