UN Secretary-General Ban Ki-moon and the Security Council have condemned the assassination of Russian Ambassador to Turkey, Andrey Karlov, in Ankara on Monday.
Ban and the Council, in separate statements, said there was no justification whatsoever for targeting diplomatic personnel and civilians.
“The Secretary-General is appalled by this senseless act of terror,” according to a statement issued by Ban’s spokesperson, Mr Stephane Dujarric.
The UN chief also expressed his deepest condolences to the family of Amb. Karlov and to the Government and people of the Russia.
Ban said he was “following the unfolding situation closely” and wished those who were reportedly injured in the attack a speedy and full recovery.
In a separate statement, the Security Council, while condemning the deadly terrorist attack, expressed its deep condolences to the family of the ambassador and the Russian Government.
The Council reiterated the need to bring the perpetrators, organisers, financiers and sponsors of terrorist attacks to justice.
Council members reaffirmed that terrorism in all forms constitutes one of the most serious threats to international peace and security, and that any acts of terrorism are criminal and unjustifiable.
The 15-member Council also stressed the fundamental principle of the inviolability of diplomatic agents and consular officers and the obligations.
These include, under the 1961 Vienna Convention on Diplomatic Relations and the 1963 Vienna Convention on Consular Relations, to take all appropriate steps to prevent any attack on diplomatic agents and consular officers.
U.S. Secretary of State John Kerry, in a statement, also described the attack as “despicable”.
“The United States condemns the assassination today in Ankara of Russian Ambassador Andrey Karlov.
“Our thoughts and prayers are with his loved ones, the Russian people, and with the other victims who were injured in this shooting.”
The U.S. offered to assist Russia and Turkey to unravel the mystery behind the attack.
“We stand ready to offer assistance to Russia and Turkey as they investigate this despicable attack.
“This attack was also an assault on the right of all diplomats to safely and securely advance and represent their nations around the world,” Kerry said.
Turkish policeman shot dead Russia’s ambassador to Turkey, Andrei Karlov, apparently in protest at Russia’s involvement in Aleppo.
The killer was identified as Mevlut Mert Aydintas, 22, a member of the Ankara riot police. It was not clear if he had links to any group.
The incident happened on Monday a day after protests in Turkey over Russian support for Syrian President Bashar al-Assad.
Turkey’s President Recep Tayyip Erdogan said the attack was aimed at hurting ties with Russia.
Erdogan spoke to Russian President Vladimir Putin by phone and, in a video message, said that they both agreed it was an act of “provocation”.
He said that those who wanted to harm relations between the two countries “would not achieve it”.
