President Barack Obama has said that India and Pakistan should reduce nuclear threat.
Obama said, "we need to see progress in Pakistan and India" and "make sure that as they develop military doctrines that they are not continually moving in the wrong direction," at Nuclear Security Summit in Washington
According to NDTV, US president expressed serious concerns about "nuclear arsenals" growing in some countries, and added that those with small tactical nuclear weapons could be at greater risk of theft.
His remarks are believed to be a direct reference to Pakistan, which has been amassing small, tactical nuclear weapons apparently as what it sees as a defence to India's Cold Start doctrine.
However, US and the larger international community see these weapons as highly vulnerable to theft from terrorist networks such as ISIS.
The channel also said that case of terrorist theft was discussed by world leaders at the summit. Session focused on the global response to a terrorist getting access to Pakistan's nuclear weapons, through a gap in security protocols.
Report further said, Pakistan, has not agreed to decrease its tactical nuclear weapon arsenal and maintains its security procedures are sufficient.
