Deshmukh, Mukesh Ambani in Indian Mujahideen's e-mail

The e-mail of Indian Mujahideen, which has claimed responsibility for the terror strikes in Ahmedabad, has warned of dire consequences to some politicians and business heads, prompting authorities to increase their security.

In its 14-page email, the militant outfit, believed to be a shadow amalgam of the banned Students Islamic Movement of India and Pakistan-based Lashker-e-Tayiba, warned Maharashtra Chief Minister Vilasrao Deshmukh and his deputy R R Patil of dire consequences over the alleged targeting of minority communities in that state.

"We wonder at your memory. Have you forgotten the evening of July 11, 2006, so quickly and so easily?" the e-mail warned.

Reliance Industries Limited head Mukesh Ambani also figured in the e-mail in which he was asked to "think-twice" before "usurping and building a citadel on a land in Mumbai that belongs to the Waqf board.

"Lest it turns into horrifying memories for you which you will never ever forget," the e-mail said.

There was a warning for the UP Bar Council too for their repeated stand of not taking up cases of Muslims.

For the high-profile VIPs and VVIPs on the Central security list, preventive measures have already been placed and for those on state list, authorities concerned have been asked to take up necessary steps, sources in the Union Home Ministry said in Delhi.
