SEOUL, South Korea — Evidence overwhelmingly proves North Korea fired a torpedo that sank a South Korean warship in March, killing 46 sailors, investigators said today.

South Korean President Lee Myung-bak vowed "stern action" for the provocation and called an emergency security meeting for Friday, the presidential Blue House said.

"(We) will take resolute countermeasures against North Korea and make it admit its wrongdoings through strong international cooperation," Lee told Australian Prime Minister Kevin Rudd in a phone conversation, the presidential office said.

The long-awaited investigation results from a multinational team said a torpedo caused a massive underwater explosion that tore the Cheonan apart on March 26.

Fifty-eight sailors were rescued from the frigid Yellow Sea waters near the Koreas' maritime border but 46 perished — South Korea's worst military disaster since the end of the three-year Korean War in 1953.

Fragments recovered from the waters near the Koreas' maritime border indicate the torpedo came from communist North Korea, investigators said.

Pieces recovered at the sinking site "perfectly match" the schematics of the torpedo included in introductory brochures provided to foreign countries by North Korea for export purposes, chief investigator Yoon Duk-young said.

A serial number on a torpedo fragment also was consistent with markings from a North Korean torpedo that South Korea obtained years earlier, Yoon said.

ANKARA, Turkey — Rescuers today found the bodies of 28 miners deep in a damaged coal mine, making the methane gas explosion three days earlier one of the deadliest mine accidents in Turkey in recent years.Energy Minister Taner Yildiz said rescuers were still trying to find two miners still missing in the Karadon mine, near the northern Black Sea port of Zonguldak.The explosion Monday buried the miners some 1,770 feet underground. Eleven miners were evacuated shortly after the explosion.Some 400 mine rescuers had been working in shifts trying to reach the missing miners since then, their work hampered by collapsed rocks."We are very saddened and extend our condolences to the miners' families and the whole of Turkey," Labor Minister Omer Dincer said, announcing the deaths alongside Yildiz. "We are doing our best for the other (missing) miners."The rescuers were able to reach the bodies after they fixed a platform used to lower the miners, Yildiz said. They used the elevator at "great risk" to their own safety, he said.The minister said the miners appeared to have died of carbon monoxide poisoning, adding that autopsies would be conducted to establish the exact cause of death.Authorities have said an electrical malfunction might have caused the explosion and an investigation has been launched to see if any safety rules may have been violated.

The group later ate lunch together at a feast of rice, kebabs and other traditional Middle Eastern dishes.Iran detained the three Americans — Sarah Shourd, 31; her boyfriend, Shane Bauer, 27; and their friend Josh Fattal, 27 — along the Iraqi border in late July and have accused them of entering from Iraqi territory and spying.
