Indian security forces and the Indian army responded quickly to keep order. More than 40 unarmed protesters were killed and at least 300 were detained. The largest protests saw more than a half million people waving Pakistani flags and crying for freedom at a rally on 18 August, according to "Time magazine". Pro-independence Kashmiri leader Mirwaiz Umar Farooq warned that the peaceful uprising could lead to an upsurge in violence if India's heavy-handed crackdown on protests was not restrained. The United Nations expressed concern at India's response to peaceful protests and urged investigations be launched against Indian security personnel who had taken part in the crackdown.
