An annual international commemoration will take place in the South Korean city of Busan later this week to remember U.N. veterans fallen during the 1950-53 Korean War, the veterans ministry said Tuesday. The International Memorial Day for U.N. Korean War Veterans is scheduled to be held at the U.N. Memorial Cemetery in Korea in the port city, some 330 kilometers southeast of Seoul, on Wednesday, the ministry said in a release. Seoul hosts the event Nov. 11 every year to honor the veterans who fought alongside South Korean forces under the U.N. flag against the Soviet-backed North Korea during the three-year conflict. The war ended in an armistice, not a peace treaty. Under the theme "A Moment to Be One, Turn Toward Busan," the ceremony will bring together around 1,000 attendees, including Korean War veterans and their families from six participating nations, foreign diplomats based in Seoul, U.N. Command service members and members of the general public. At exactly 11 a.m., a memorial siren will echo throughout Busan for a one-minute silence to honor the fallen soldiers. A 21-gun salute
