World Powers Express Alarm at Korean Artillery Duel VOA News 23 November 2010 Major powers around the world have expressed deep concern at a deadly exchange of artillery fire between North and South Korea. Some of the toughest language came from the United States, which condemned North Korea for attacking the South and demanded that it halt its "belligerent action." Washington also renewed its commitment to defend South Korea from any attack. China, on the other hand, said both Koreas needed to do more to maintain peace between them, and called for an urgent resumption of six-party talks on North Korea's nuclear programs. Russia, Britain and Germany also commented, expressing varying degrees of alarm. Russian Foreign Minister Sergei Lavrov said he sees a "colossal danger" that the fighting will escalate, while British Foreign Secretary William Hague condemned Pyongyang for its "unprovoked attack." German Foreign Minister Guido Westerwelle said he is "very worried" by the artillery exchange. North Korea fired more than 50 shells into a populated border island while South Korean troops were conducting a military exercise, killing two soldiers and wounding both soldiers and civilians. Pyongyang said the strikes were made in response to South Korean fire - presumably during the military drill. The South said its troops were firing away from the North Korean mainland.
