With President Vladimir Putin on a landmark visit in India, New Delhi has confirmed that deliveries of Russian S-400 missile defense systems, which caused a furious backlash from Washington, are going ahead as planned.

Both countries signed a $5.4-billion deal for five of the surface-to-air systems in 2018.

“Supplies have begun this month and will continue to happen,” the Indian foreign ministry said, as Putin arrived on Monday. (RT)
