Pakistan militants lurking in the shadows

As Nato forces prepare to leave Afghanistan, the Taliban remains a threat and another militant group in the region also continues to cause concern.

Five years ago in the Indian city of Mumbai, attacks on the railway station, luxury hotels and a Jewish cultural centre left more than 160 people dead.

The Islamist militant group responsible - Lashkar-e-Taiba - has been largely quiet outside Pakistan's borders since then, but as the BBC's Brajesh Uphadyay reports, there are fears it is growing in strength.
