At least 32 people have been killed and 200 others wounded in a military operation by Azerbaijan in the disputed Nagorno-Karabakh region, according to an official in Armenian-controlled territory there.

Azerbaijan’s defense ministry said Tuesday it had begun an “anti-terrorist” campaign in the region, an ethnic Armenian enclave that is internationally recognized as part of Azerbaijan and which has been the cause of two wars between the neighbors in the past three decades, most recently in 2020.

Gegham Stepanyan, the ombudsman in Nagorno-Karabakh, said at least seven civilians had been been killed, including two children, and at least 35 others were injured in the operation after Armenian media and local authorities reported heavy bombardment of the regional capital of Stepanakert.
