BAKU: Azerbaijan on Friday said it was evacuating staff from its embassy in Tehran, blaming Iran for a terrorist attack in which the head of security was killed and two guards wounded, reports AFP.
Tehran's police chief said the man who carried out the attack was motivated by personal reasons.
He said a recent anti-Azerbaijani campaign in Iranian media had encouraged the attack.
Hacizada later told Turkish TRT Haber TV station that the embassy staff are being evacuated from Iran.
Azerbaijani President Ilham Aliyev said on Twitter I strongly condemn the terrorist attack.
In a statement earlier on Friday Azerbaijan's foreign ministry said a man armed with a Kalashnikov killed the head of the diplomatic mission's guard.
It said that two guards injured by the attacker were in a satisfactory condition and an investigation had been launched.
Iran's foreign ministry spokesman, Nasser Kanani, said Tehran strongly condemned the armed attack... which unfortunately resulted in the death of one person.
According to the preliminary investigation, these are personal motives, he added.
Iran is home to millions of Turkic-speaking, ethnic Azerbaijanis and it has long accused Baku of fomenting separatist sentiments in its territory.
Relations between the two countries have traditionally been sour, with the former Soviet republic a close ally of Iran's historical rival Turkey.
Tehran also fears that Azerbaijani territory could be used for a possible offensive against Iran by Israel, a major supplier of arms to Baku.
