Leaders pledge nuclear security

Pledges made to prevent atomic material from falling into hands of "non-state actors".

    World leaders gathered in the US capital have agreed to take steps to prevent nuclear terrorism, which they saw is one of the most challenging threats to global security.

    In a final declaration the 47 nations at the security summit in Washington issued a call to secure all vulnerable nuclear material in four years.

    Some bilateral agreements on the sidelines were also announced - among them a deal signed by Russia and the US to destroy tonnes of weapons-grade plutonium.
