Rescuers have recovered four bodies believed to be crew members of a plane that crashed in the Gulf of Tonkin last week.
The bodies were found over the past two days about 15 nautical miles (28 kilometers) southeast of Bach Long Vi Island in the Gulf.
One of them carried identity document of Maj. Nguyen Van Chinh, one of the nine crew members onboard the Airbus CASA 212, which went down on Jun. 16 while looking for a missing fighter aircraft.
The Russian-made Sukhoi Su-30 MK2 crashed on Jun. 14 on a training mission, according to the defense ministry. One pilot was rescued and the body of the other was found on three days later.
The ministry said search vessels on Thursday found some wreckage of both planes.
But the search will be hampered by bad weather in the hours to come as a tropical depression has been formed in the area, according to search and rescue authorities.
