Indian authorities withdrew police protection for five separatist leaders in Kashmir on Sunday amid mounting fallout from a suicide bombing that killed 41 soldiers in the disputed region. New Delhi has vowed to retaliate after a van packed with explosives ripped through a convoy transporting 2,500 soldiers across the Indian-administered territory on Thursday, the deadliest-ever attack in a 30-year-old armed conflict. Indian officials said police protection had been withdrawn for Muslim cleric Mirwaiz Umar Farooq and four other leaders.
