India's Prime Minister Narendra Modi met President Vladimir Putin in Moscow on Tuesday, deepening ties between the two nations as Western leaders gathered at a NATO summit in Washington and Russia stepped up attacks in Ukraine with deadly missile strikes.

While leaders — including President Joe Biden and Britain's newly elected Prime Minister Keir Starmer — prepared to mark 75 years of the world's biggest security organization, and reassure Ukraine of NATO's support, Putin and Modi were pictured viewing an exhibition of nuclear technology in space.
