SEOUL, South Korea — North Korea test-fired five short-range missiles into the sea Sunday in its second such weapons test this year, a South Korean defense official said.

The tests come amid dimming prospects for the resumption of high-level talks between the rival countries.

The missiles, fired from a North Korean coastal town, flew about 125 miles before landing in waters off the country’s east coast, a South Korean Defense Ministry official said.

North Korea routinely tests missiles, rockets and artillery, but the latest launches came with the two Koreas at odds over terms for a possible summit meeting between their leaders. The two countries last month floated the idea of the summit, which would be the third such meeting since they were divided 70 years ago.

The South Korean defense official said Sunday’s launches were the North’s second missile firings this year.
