A decades-long dispute over territory in the southern Caucasus has led to open hostilities between Azerbaijan and Armenia this past week. Azerbaijan's second-largest city, Ganja, came under attack Sunday, with government officials saying Armenia had launched missiles into residential areas. Armenia has denied the charges; the leader of the territory at the center of the dispute said his forces were responsible for the attack.
Azerbaijani officials said one civilian was killed in the attack, and 32 more were injured.
"Opening fire on the territory of Azerbaijan from the territory of Armenia is clearly provocative and expands the zone of hostilities," Azerbaijani Defense Minister Zakir Hasanov said in a statement, the Associated Press reported.
The "insane Political-military leadership of Armenia" is a threat to regional peace and security, Hikmet Hajiyev, an aide to Azerbaijan's president, wrote on Twitter. "Azerbaijan retains its right to take adequate measures against legitimate military targets to defend civilians," he added.
Armenia denied the charges. "No fire of any kind is being opened from the territory of Armenia in Azerbaijan's direction," the nation's defense ministry said.
