South Asian arms race raises risk of nuclear war - IISS think tank

LONDON (Reuters) - An arms race in South Asia and Pakistan's development of tactical "battlefield" nuclear weapons are increasing the risk of any conflict there becoming a nuclear war, the International Institute for Strategic Studies (IISS) said on Thursday.

Noting that Pakistan looks set to overtake Britain as the owner of the world's fifth-largest nuclear weapons stockpile, it urged India and Pakistan to improve their communications to avoid any fatal misunderstandings during a crisis.
