Four years ago, 40 men, mostly from Punjab, set off for war-torn Iraq not knowing that they would never come back. They had gone there as construction labourers to support their families back home. What they saw instead was the blood and gore that the ISIS unleashed as it captured Mosul. The men captured - that was the last their families heard from them. On Tuesday, external affairs minister Sushma Swaraj told the country that all 39 of them were dead. Their bodies were found at a mass grave in Badush, a small village near Mosul.
