Pakistani officials say insurgents who attacked a passenger train carrying 440 people in the southwest killed 21 hostages but security forces rescued the others.

QUETTA, Pakistan (Reuters) -Dozens of people rescued from a train hijacked by separatist militants in southwestern Pakistan arrived on Thursday in the city of Quetta, hours after security forces killed all 33 attackers to end a day-long standoff.

Pakistan freed 190 hijacked train passengers held hostage Wednesday as the battle to free remaining hostages held by the militant group Baloch Liberation Army continued.
