The head of NATO's cyber defense unit, Christian-Marc Liflander said that the S-400 system is not compatible with the air defense systems now used by the alliance.
In a closed door meeting, Pompeo and fellow foreign ministers of the military pact forged a consensus on the need for a response to "Russian aggression", a United States official said, adding that Pompeo pressed allies to raise military budgets.
He expresses hope that these contradictions between the parties will be resolved as soon as possible.
The NATO-Russia Council has not convened this year and the March 4 poisoning of an ex-Russian spy in Britain plus the chemical attack in Syria that has been blamed on Moscow ally Syrian President Bashar Assad underline the need for more talks, he said. Two-thirds of agencies using email fraud tool Senate confirms Pompeo as Trump's new secretary of State MORE, laid blame for the attack at Russia's feet before his firing by Trump last month.
Turkey's plans to purchase weapons from Russian Federation has unnerved some North Atlantic Treaty Organisation members, which have been building up forces on NATO's eastern flank because of what they perceive as a growing threat from Russian Federation. "The work that's being done here today is invaluable", Pompeo said.
According to the report, officials of the US-led military alliance have also warned Ankara about unspecified consequences of purchasing the S-400, insisting that the system is incompatible with the NATO's systems. That commitment was made in 2014 and thus far only six of the 28 countries who made the pledge meet the goal. "And we have renewed our commitment, including with significant troop increases and financial support".
Discussions will also be held on other key worldwide issues, including the Iran nuclear deal, a training mission for Iraq, closer cooperation with the European Union and the prospects for peace in Afghanistan. Relations with the latter are notably strained.
The daily also quoted the US NATO envoy as saying, "Turkey has been a strong ally for us in NATO, but we are very anxious at the point that we have come to".
Earlier in the week, U.S. Permanent Representative to NATO Kay Bailey Hutchinson said Turkey purchasing the missile defense system from Russian Federation is worrying for her country and added that there would be "serious consequences". "We agreed that our policy of a dual approach - strong deterrence and defense in conjunction with the dialogue remains in force", - he said in Brussels, UKRINFORM writes. From Brussels, Pompeo will travel on to the Middle East, visiting Saudi Arabia, Israel and Jordan, where the future of the Iran nuclear deal and the conflict in Syria will be significant agenda items, officials said.
