Five years after the horrific Mumbai terror attacks, Lashkar-e-Taiba (LeT) is stronger than ever and remains the "favoured instrument" of Pakistani military and the ISI against India, US experts have said.

"Lashkar-e-Tayyiba is stronger today than ever. It has a secure stronghold in Pakistan, networks in the Gulf for fundraising and cells in the Pakistani diaspora in the UK, UK and elsewhere. It is a major threat to India, America and others," Bruce Riedel, the former CIA analyst and a top American expert on South Asian counter-terrorism issues said.

Experts and ex-administration officials reiterated the ISI of Pakistan continues to support LeT, which they warned now poses an equal threat to the US and India.
