SEOUL (Reuters) - South Korean Foreign Minister Yu Myung-hwan has resigned following accusations of nepotism involving his daughter's employment, government sources and the ministry said on Saturday.

 ''The foreign minister's resignation has been accepted by the president,'' said a presidential source who spoke on condition of anonymity. '

'The foreign minister has resigned to accept responsibility for all the commotion caused by the ministry employing his daughter on a full time basis.'' Yu's daughter, Yu Hyun-sun, was employed at the foreign ministry between 2006 and 2009, said a foreign ministry source.

She was to sign a contract on Aug. 31 with the foreign ministry to work on trade matters, but public criticism forced her to not take up the position. Yu Myung-hwan, 64, is one of President Lee Myung-bak's longest serving ministers having served in the government since February 29, 2008.

VIETNAM MASS GRAVE FOUND

HANOI, Vietnam (AP) - The remains of 44 communist soldiers believed killed during the Vietnam War's Tet Offensive have been found in a mass grave, bringing the number of remains recovered at the site to 74, a military official said Saturday.

 The soldiers were believed to have been killed during an assault on an American base during what was seen by many as the Vietnam War's turning point. Thousands of Viet Cong guerrillas attacked major towns across southern Vietnam during the Tet Offensive in January 1968.

 Quang Tri was the front line, and fierce fighting took place there. Maj. Col. Tran Trong Trung of the provincial military command said none of the remains had been identified, but the site includes personal effects such as watches, belts and raincoats.

Authorities had searched unsuccessfully for the grave in central Vietnam's Quang Tri province for three years based on information provided by American veterans who said some 158 soldiers may be buried there, said Trung.

WILDFIRE PARKED BY SIGNAL BLAZE

CAMPO, California (AP) - Authorities say a wildfire burning in rural San Diego County was sparked by two illegal immigrants who set a signal fire after they got lost.

California Department of Forestry and Fire Protection Battalion Chief Nick Schuler says the migrants made a cell phone call to Mexico's emergency dispatch system Thursday afternoon saying they'd been lost for two days, were dehydrated and were going to set a signal fire so rescuers could spot them. Schuler says remnants of a campfire were found, but there was no sign of the migrants.

The fire, between Campo and Potrero, has grown to 822 acres (332 hectares) and is 42 percent contained. Full containment is expected Sunday. No structures are threatened, no roads are closed and there have been no injuries.

SEA LION MAULS 11-YEAR-OLD BOY

SYDNEY (AP) - An 11-year-old boy was recovering Saturday after a sea lion mauled him at a popular Sydney zoo's aquarium show as horrified visitors looked on.

 The boy, identified by his stepmother as Jack Lister, had been invited by zookeepers to meet the 8-year-old female sea lion during the Taronga Zoo's seal and sea lion show on Friday. After feeding the animal, Jack mistakenly followed it off the stage, which spooked it, zoo officials said.

The sea lion bit the boy and left several puncture wounds on his stomach. Jack had abdominal surgery Friday night and was in stable condition at a hospital. Jack's stepmother, Dalitta Wright, told Sydney's The Daily Telegraph in a story published Saturday that the attack was sudden.

``I can only assume he was going for the smell of the fish. Jack pulled himself away and it then lunged for his back,'' said Wright, whose family was visiting Sydney from the northeast city of Cairns. ``It all happened so quickly. ... It was quite traumatic.''
