SIRTE, Libya -- The bodies of 267 people, many of them believed to have been executed, were found in Sirte, the hometown of former Libyan dictator Muammar Qaddafi, a local newspaper reported Wednesday.

Most of those found dead were supporters of Qaddafi, a Red Cross source told online Libyan newspaper Qurynanew.

The source said that most of the bodies were executed and buried in mass graves in Sirte and the surrounding area.

Officials from Benghazi and Sirte numbered and photographed the bodies before burying them and will store the information in an archive to show the victims' families, the report said.

The Transitional National Council (TNC) pledged to investigate the deaths and punish the perpetrators, the source added.

It came a day after Qaddafi was buried at a secret location in the Libyan desert.

The fallen despot was killed Thursday after TNC fighters hauled him out of a drainpipe on the outskirts of Sirte. He was then shot, though the exact circumstances surrounding his death remain unclear, with officials saying he was caught in crossfire and unconfirmed reports saying he was executed.
