Islamists, separatists suspected in Assam attack

Indian authorities suspect that Islamist groups in collusion with separatist militants carried out coordinated bomb blasts in the Assam state that killed 77 people and wounded more than 320.

Separatist movements have riddled India's remote northeast for decades, but the level of sophistication and precision of Thursday's bombings also echo similar blasts across India over the past year which have been blamed on Islamist groups.

Bangladesh-based Harkat-ul-Jihad al Islami (HuJI) is one of the main suspects in Thursday's attack. Police say the Islamist group could have sought to avenge attacks on Muslim settlers by indigenous tribes that killed at least 47 people last month.
