A suspected bomb went off on Saturday in Hanoi, killing four and injuring six others.
The location of the explosion, which happened at 3:00 pm, is the Van Phu residential area in Ha Dong District on the outskirts of the Vietnamese capital.
Witnesses at the scene reported to have seen a scrap vendor who lived in the area carrying an object shaped like a 12kg gas tank out on the sidewalk of his scrap procurement shop prior to the explosion.
The man was reportedly sawing the object when it went off, leaving a 3m2-wide crater on the sidewalk.
The explosion completely destroyed the ground floor of the shop, while damaging 36 other apartments in the area as well as numerous passing vehicles.
Four were killed in the deadly blast, including the scrap vendor and some passers-by, while six others were wounded and immediately hospitalized.
Among those losing their lives were a 31-year-old mother and her 7-year-old daughter who were passing by the site at the time of the explosion.
