Russia said on Tuesday it plans to deliver its S-400 missile defense systems to Turkey in July, setting the clock ticking on a U.S. threat to hit Ankara with sanctions if it goes ahead with a deal that has strained ties between the NATO allies.
The leaders of the U.S. Senate Foreign Relations and Armed Services Committees warned Turkey on Tuesday that it risked tough sanctions if it pursued plans to purchase Russian S-400 missile defense systems, and they threatened further legislative action.
