Indonesia's vice president is calling on Islamic leaders to spread messages about a tolerant Islam to curb extremism that often springs from misinterpretation of Islamic teachings.

Vice President Jusuf Kalla said he believes that youths who don't have deep faith are susceptible to be militants, not for wealth or political cause, but rather as a "shortcut" to heaven.

He spoke at the International Summit of the Moderate Islamic Leaders, which opened Monday in Jakarta.

The meeting organized by Nahdlatul Ulama, Indonesia's largest Muslim organization, is expected to produce a message about the importance of promoting a peaceful Islam to combat radicalism worldwide.

Indonesia is the world's most populous Muslim nation. Militants have carried out a spate of attacks including the 2002 Bali bombings that killed 202 people, mostly foreign tourists.
