The International Committee of the Red Cross says at least 13 mass graves have been found in Libya over the past three weeks as the search for Moammar Gadhafi continues.

The Geneva-based Red Cross says its staff assisted in the recovery of 125 bodies found at 12 different sites in and around Tripoli.

It says remains of 34 people were also recovered from a site in the Nafusa mountain village of Galaa in western Libya.

ICRC spokesman Steven Anderson said Wednesday that more mass graves are being found every week.

The aid group says it is helping ensure the remains are properly recovered so that the identities of the dead can be established and relatives informed.

It said it is not involved in collecting evidence that could be used in war crimes or other legal proceedings.

Fighting continues in search for Gadhafi

The Red Cross announcement follows the pounding by NATO warplanes of targets in a number of strongholds of support for Gadhafi.

The alliance said Tuesday that airstrikes struck one radar system, eight surface-to-air missile systems, five surface-to-air missile trailers, one armed vehicle and two command vehicles a day earlier near Gadhafi's hometown of Sirte on the Mediterranean coast.

NATO, which has played a crucial role in crippling Gadhafi's military capabilities over the seven-month Libyan civil war, also said it struck six tanks and two armoured fighting vehicles in Sabha in the southern desert.

Those two cities, along with Bani Walid, southeast of the capital, are the primary bastions of Gadhafi loyalists remaining in the country more than three weeks after revolutionary forces captured Tripoli Aug. 21, effectively bringing an end to Gadhafi's nearly 42-year rule.
