SEOUL—North Korea fired two unidentified projectiles toward the waters off its east coast, according to South Korea’s military, in another weapons test aimed at increasing pressure on the U.S. to provide sanctions relief amid stalled denuclearization talks.

Seoul’s Defense Ministry on Thursday said the North conducted the test at about 4:59 p.m. local time a few miles from the North Korean port city of Hamhung, near a town believed to host a military airfield.

The latest provocation marks the North’s 14th weapons test of this year, according to South and North Korean government announcements, and follows a visit by leader Kim Jong Un to a military base near the Yellow Sea days earlier to oversee the testing of coastal artillery.

Experts said the tests signal Pyongyang’s growing impatience with Washington, which has been reluctant to ease sanctions that have hurt North Korea’s economy. Mr. Kim has repeatedly said economic growth is a major policy goal this year.

“North Korea is trying to tell the U.S. these weapons tests can become much more frequent, if the Americans don’t yield concessions,” said Shin Beom-cheol, a former adviser to the South Korean government and now a senior researcher at the Seoul-based Asan Institute, a private think tank.

“They are also separately testing the reactions of the U.S. and South Korean militaries to these weapons tests,” he said.
