As a sign of mourning the death of 30 Iranians and two Bangladeshi nationals, Iran's flag at Iranian Embassy in Tokyo has been flown at half-mast on Tuesday and Wednesday, IRNA reported.
The statement of the embassy said the memorial book will be open on Tuesday and Wednesday.
An Iranian tanker carrying gas condensates collided with a Chinese freight ship in East China coast on January 6, and all the 32 crew members went missing. Three bodies were later found during a rescue operation.
The 30 Iranians and the two Bangladeshi sailors, who were crew members, had been reportedly killed due to inhaling toxic gases. The size of the fire and the volume of smoke hampered the rescue mission and made it impossible to approach the vessel.
The tanker which was carrying 11,510 tons of gas condensates, 1,956 tons of mazut and 118 tons of diesel sank completely in China Sea on Sunday.
