A group of militants seized a Peshawar-bound train, igniting a 36-hour hostage crisis, but this attack is part of a decades-long insurgency rooted in the Baloch separatist groups' violent struggle for an independent state.

India on Friday strongly rejected Pakistan's foreign office claim alleging its possible involvement in the Jaffar Express train hijacking in Balochistan.Ministry of external affairs spokesperson Randhir Jaiswal said,

The Baloch Liberation Army claimed responsibility, alleging that 90 military personnel had died in the attack.

Separatist militants drove a vehicle laden with explosives into a paramilitary convoy, killing at least five in southwestern Pakistan, officials said on Sunday (March 16), just days after the same group hijacked a train and held hostages for 36 hours.
