Over 60 countries including India will participate in a White House summit on "countering violent extremism" beginning today in the backdrop of alarming growth of the Islamic State and recent terrorists' attacks in France and Denmark, senior administration officials have said.

While the first two days of the three-day summit are primarily focused on domestic extremism given that there was substantial increase in home grown terrorism, the final day, Thursday would see full participation of more than 60 countries including several ministers to focus on foreign fighters among others.

India, which for the past several decades has been a victim of foreign supported terrorism and faces a challenge of domestic violent extremism that include Naxals and Maoists in particular, would be represented by R N Ravi, chairman of the powerful joint intelligence committee. "It's a very full and very ambitious agenda to expand and deepen our global coalition to counter and prevent violent extremism," a senior administration official said yesterday.

The conference would highlight domestic and international efforts to prevent violent extremists and their supporters from radicalising, recruiting, or inspiring individuals or groups in the US and abroad to commit acts of violence, efforts made even more imperative in light of recent, tragic attacks throughout the world.

Led by US President Barack Obama, top officials of his administration including Secretary of State John Kerry, National Security Advisor Susan Rice would be addressing the White House Summit. Obama would be addressing the gathering twice in the summit
