Anger and protests over the government's secret execution of a Kashmiri man convicted in a deadly attack on India's Parliament has stirred fears the volatile region could again descend into a cycle of violence after two years of relative peace.

Kashmir has been rocked by anti-India protests, despite a rigid curfew, since Mohammed Afzal Guru was hanged in New Delhi early Saturday. Three protesters have been killed so far in clashes with security forces.

Tens of thousands of troops patrolled the streets of Indian-controlled Kashmir on Tuesday, confining residents to their homes.

Omar Abdullah, Indian Kashmir's top elected official, expressed concerns that Guru's hanging could lead to a new round of unrest.
