A tired but smiling 85-year-old US veteran detained in North Korea for several weeks returned home today to applause from supporters, yellow ribbons tied to pillars outside his home, and the warm embrace of his family. Merrill Newman arrived at the San Francisco airport after turning down a ride with Joe Biden. He emerged into the international terminal smiling, accompanied by his son and holding the hand of his wife amid applause from supporters. "I'm delighted to be home," he said. "It's been a great homecoming. I'm tired, but ready to be with my family."
