India, July 7 -- NATO Secretary-General Mark Rutte on Monday demanded that the allies put forward "clear, concrete and credible plans" to reach the organisation's spending targets at its annual summit in Ankara.

Rutte made the remarks in the Turkish capital come ahead of a two-day summit starting on Tuesday that comes at a time crucial time for the alliance, with the United States scaling down its security role in Europe. Washington has been pressing allies to shoulder more of the spending burden. The 32 nations agreed last year to invest 5 per cent of their gross domestic product on defence - 3.5 per cent on their defence budgets and 1.5 per cent on roads and ports so troops and equipment can move faster in times of conflict.
