In a gruesome case of domestic violence, a 50-year-old Myanmarese national killed his estranged wife by setting off an explosive under her pillow.

The man, H Ngunchhuma, placed a gelatine stick under the pillow of his 45-year-old wife Lenpari when she was sleeping at the home of their eldest son on Friday, Aizawl district SP Lalbiakthanga Khiangte said.
