Four Naga civilians, including a woman and her son, were killed when suspected militants ambushed two vehicles on National Highway 202 in Manipur’s Ukhrul district, on Friday afternoon.

Police said the vehicles were attacked near New Haven, about 82 km northeast of Imphal, and that additional police, Border Security Force (BSF), army and Assam Rifles units were rushed to the area. Attacks on civilian vehicles on the same highway have recurred: in April, two Naga men, including an ex-serviceman, were killed in a similar ambush.
