Two Vietnamese workers in Angola were shot dead by robbers last week, officials have confirmed.
The Vietnamese embassy in the African country said some robbers beat and shot Dang Quoc Nghia, 44, on March 3 and Nguyen Viet Hau, 33, on March 5 after they refused to give them money.
Both men came from Ha Tinh Province in central Vietnam.
Authorities from Ha Tinh said they went to Angola three years ago.
Hau is survived by his wife and two children, they said.
The embassy is raising funds to send the bodies home as both are illegal workers and are not entitled to any official support.
Another worker from Ha Tinh was also killed in Angola last October in a similar circumstance.
Vietnamese labor suppliers were allowed to send workers to Angola in early 2014.
But many people in central Vietnam had started going there to escape poverty several years earlier with short-term, unofficial contracts at construction sites. They face daily threats from armed robbers on the street.
At least 34 workers from Ha Tinh and neighboring Nghe An Province have died in Angola since March 2013 due to accidents, illnesses and robberies, according to official data.
