SEOUL, April 11 - South Korea's acting president warned on Tuesday of "greater provocations" by North Korea as tension on the Korean peninsula rises over concern the North may conduct a test of its military hardware in coming days.
A US Navy strike group led by a nuclear-powered aircraft carrier is en route to the western Pacific with talk of military action by the United States gaining traction following its strikes last week against Syria.
South Korean acting President Hwang Kyo-ahn ordered the military to intensify monitoring of the North's activities and to ensure close communication with the ally the United States.
"It is possible the North may wage greater provocations such as a nuclear test timed with various anniversaries including the Supreme People's Assembly," said Hwang, acting leader since former President Park Geun-hye was removed over a graft scandal.
The North convenes a Supreme People's Assembly session on Tuesday, one of its twice-yearly sessions in which major appointments are announced and national policy goals are formally approved.
