The Telegraph:
Turkey is to sign a new contract for S-400 missile-defense systems with Russia, according to Moscow, which would risk further souring ties with the US and could trigger threatened sanctions.
Ankara received the first batch of Russia’s surface-to-air missile systems systems in July, prompting the US to kick Turkey off its F-35 fighter jet programme.
The Trump administration warned Ankara it could face sanctions, but said Ankara could be spared if it does not activate the S-400 system.
