Pakistan has long been accused of supporting militant groups operating in Kashmir.
As a fledgling peace process between India and Pakistan developed in the years since the 11 September 2001 attacks in the US, it was widely believed that Islamabad's support for militancy had declined.
This has changed once again. Since 2009 militant activity has been on the increase in the Kashmir region.
After the deadly Mumbai (Bombay) attacks of 2008 India called off peace talks. Dialogue resumed in February 2010 but the issue of militancy allegedly supported by Pakistan remains high on India's agenda.
Pakistan's government denies any knowledge of Kashmir militant groups increasing their activities.
Initially militant groups in Kashmir appeared to be operating on their own - but there is evidence to suggest that they are once again under the protection of Pakistan's intelligence establishment.
Training camps are once again being set up on the Pakistani-controlled side of Kashmir.
