GUWAHATI India (Reuters) - Suspected tribal rebels have shot dead 22 Muslims in attacks in India's northeasterly tea-growing state of Assam, where tension has run high during a drawn-out national election, officials said on Friday.

A dusk-to-dawn curfew was imposed on Friday and soldiers deployed in the affected parts of Assam, a remote state with a history of ethnic violence and armed groups, some fighting for greater autonomy and others for secession from India.
