The workers were Dang Quoc Nghia, 44, and Nguyen Viet Hau, 33, both Vietnamese nationals, who were in the southern African nation on valid work visas.

Nghia, from Cam Nam Village at the Cam Xuyen District of Ha Tinh Province had worked in Angola for three years while his coworker, Hau , was from Son Tho Village at the Vu Quang District of Ha Tinh Province.

The Vietnam Embassy believes that there was only one gunman involved in the shooting but said the motivation was unclear. The Embassy has started a collection to raise funds to help transport the two men’s remains home.
