GEORGETOWN, Guyana (AP) — Guyana’s government on Sunday appointed a group of international experts to investigate the recent sinking of a state ferry that killed dozens of passengers in the country’s worst maritime disaster on record.

The 87-year-old MV Barima capsized in Atlantic waters on June 18 after it departed the capital, Georgetown, en route to Port Kaituma, an Indigenous community near Venezuela.

Authorities have said they believe 179 passengers were aboard, but divers so far have found only 73 bodies, with another 76 people rescued.
