North, South Koreans Trade Heavy Gunfire

North Korean soldiers shot at least 10 mortar rounds at a South Korean border post Wednesday during a heavy exchange of gunfire - the most serious clash on the Korean peninsula in almost a year.

North Korea said several of its soldiers were wounded in the clash along the central part of the Korean border, the world’s most heavily armed.

No South Korean casualties were reported in the shooting, which each side blamed on the other.

It was the most serious armed clash since September, when a North Korean submarine was found off South Korea’s east coast.
