SEOUL: A South Korean news agency has reported that North Korea test-fired a short-range missile.

The Yonhap news agency report Monday comes just hours after the communist nation declared that it successfully conducted a nuclear test.

Yonhap said North Korea fired a ground-to-air missile with a range of 80 miles (130 kilometers) from its northeastern Musudan-ri launch site. The regime also launched a long-range rocket from that site on April 5.

South Korea's military said it was checking the report.
