The militants, who handed over their arms to authorities here yesterday, belong to the Baloch Republican Army (BRA), Baloch Liberation Army (BLA) and other separatist groups alleged to have carried out attacks on security installations and personnel in the troubled province.
Commander Southern Command Lieutenant General Amir Riaz said on the occasion that those wanting to return to normal life were welcome to do so after surrendering.
"Anyone laying down their arms would be welcomed," he said.
Balochistan Chief Minister Sanaullah Zehri alleged that for long foreign agencies had used innocent people in the province, misleading and instigating them.
A senior provincial official said so far over 1,500 militants have surrendered.
Pakistan says its borders with Afghanistan and Iran in Balochistan are being used to instigate and train people to carry out subversive activities in the country.
