Relatives of seven Japanese believed killed by tsunamis in Sri Lanka headed for Colombo on Wednesday, while the Foreign Ministry said another body believed to be that of a Japanese woman has been found there.

The dead may be some of a group of 12 Japanese nationals who remain unaccounted for there since the massive waves struck South and Southeast Asia on Sunday.

The Japanese embassy in Colombo said later in the day that one body had been confirmed to be that of a Japanese, but did not release the person's identity.
