Turkish president vows to destroy "terror corridor" in northern Syria regardless of results of the talks with the US on the Syrian safe zone.
Thursday's missile tests were the first since Kim and US President Donald Trump agreed to resume nuclear talks during an impromptu meeting last month in the demilitarised zone between North and South Korea.
"There could be more sanctions to follow, but frankly, what we’d really like is the S-400 not to become operational," US Secretary of State Mike Pompeo told Bloomberg in an interview.
"There’s no timetable on the president making a decision with the consultation of the secretary, and I want to give the president and the secretary the space to do that," State Department spokeswoman Morgan Ortagus said.
The first shipment of Russia's S-400 defence missile system to Turkey has now been completed, officials say.
Minister of Foreign Affairs Mevlut Cavusoglu said in an interview that President Donald Trump does not want to impose sanctions. He warned if the US administration takes such steps, Turkey will retaliate.
As more countries opt for the Russian long-range missiles, Washington faces a difficult choice over whether to penalise its key partners.
On Wednesday, Washington announced it was taking Turkey out of the F-35 fighter jet programme.
US President Donald Trump's comments came a day after the White House said the Turkey's purchase of Russian air defence system made Ankara's presence in the F-35 programme impossible.
'Turkey will continue to evaluate other alternatives,' says Defense Industries Presidency head Ismail Demir criticising US' announcement to remove Turkey from the F-35 programme.
Professor Edward Erickson says Turkey’s S-400 acquisition is a ‘political problem’ rather than a military problem for the US but doesn’t think Turkey’s role in NATO will be affected by the F-35 issue.
The US move to remove Turkey from its F-35 jet programme can be a major setback to NATO, as other world powers race to catch up on military aircraft technology.
