The director of the United Nations information center in Geneva said he is aware of the incident involving the alleged gunning down of a Russian Su-24 bomber aircraft, and warns that it could complicate the war on terror in Syria.
The comments came during a UN news briefing on Tuesday.
Fawzi noted that countries involved in the fight against terrorism should abide by all recognized international norms, that they should observe human rights and that their actions should be based on the rule of law.
Earlier on Tuesday the Russian Defense Ministry issued a statement on the crash of Russian Su-24 Fencer bomber jet in Syria, saying that it was most likely downed by a ground missile.
Kremlin spokesman Dmitry Peskov later reaffirmed that the jet was in Syrian airspace ahead of the crash, as previously stated by Russia's Defense Ministry, and called for patience until the exact reason for the incident was established.
