The South Korean military on Wednesday detained a man from North Korea who crossed the countries’ heavily armed land border and triggered an extensive manhunt, officials said. The New York times reports that military units had been on heightened alert since late Tuesday when signs were discovered that barbed-wire fences along the eastern border had been breached by a possible defector from the North. The military later said that its soldiers had detained a North Korean man without incident on Wednesday morning. More than 33,000 people from North Korea have defected to South Korea since a devastating famine struck the North in the 1990s.
