South Korea's military on Thursday seized a North Korean fishing boat that it said had crossed a disputed maritime border after ignoring warnings to retreat amid growing tension between the two sides, as Reuters reported. The incident comes as the North faces renewed pressure from the international community after it fired two mid-range missiles on Wednesday just as the leaders of South Korea, Japan and the United States pledged to curb its nuclear arms ambitions. In what appeared to be a show of defiance, North Korea fired two medium-range Rodong ballistic missiles into the sea, both Japan and South Korea said. The U.N. Security Council will hold closed-door consultations on Thursday to discuss a possible condemnation of North Korea's action, U.N. diplomats said.
