Azerbaijan launches operation against Nagorno-Karabakh and demands surrender

Azerbaijan has said its military measures in Nagorno-Karabakh are continuing for a second day, having launched what it calls "anti-terror" operations in the enclave.

It says it will not stop until Karabakh's ethnic Armenians surrender.

Tensions in the South Caucasus have been high for months around the breakaway region, recognised internationally as part of Azerbaijan.

Azerbaijan and Armenia last went to war three years ago.
