The dispute should be resolved politically, Ali Akbar Velayati said in an interview with the daily Keyhan.
He said according to 4 UN Security Council resolutions, Armenians have occupied parts of Azerbaijan’s soil and should withdraw to international borders.
“All of us, member states of the United Nations, must be committed to these principles,” he added.
“Just as we are against the occupation of Palestinian land by the Zionist regime, here, too, we have the same stance.”
Velayati further underlined that the Islamic Republic of Iran would spare no efforts to mediate between the two neighboring countries and help establish peace.
Since late September, heavy clashes have been underway between Azerbaijani and Armenian military forces over the disputed Nagorno-Karabakh region. Both sides blame each other for initiating the fighting in the Caucasus Mountains.
Hundreds have been killed in the worst spate of fighting between the two former Soviet republics since the 1990s.
For years, the two neighbors have been locked in a conflict over Azerbaijan’s breakaway region of Nagorno-Karabakh mainly inhabited by ethnic Armenians. Though a ceasefire was agreed in 1994, Baku and Yerevan continue to accuse each other of shooting attacks around the enclave.
