North Korea on Sunday test-fired yet another missile according to South Korean news agency Yonhap, marking what would be its seventh missile test since the turn of the year.

According to AFP, Yonhap, citing South Korean military sources, reported early on Sunday morning that Pyongyang had launched an “unidentified projectile” into the East Sea.

The report comes on the back of two missile tests that were conducted by Pyongyang over the past week. One test was conducted on Tuesday, while another was carried out on Thursday.

The two tests were initially detected by South Korea and Japan’s military, and North Korea on Friday officially confirmed that they had taken place.

Pyongyang further added on Friday that the tests had been successful, and vowed to ramp up the production of more powerful missiles, as well as develop its nuclear arsenal.

North Korea on January 5 and 11 claimed that it had successfully test fired hypersonic missiles. Subsequently, Pyongyang tested short range ballistic missiles launched from a rail car on January 14,  and followed it up with a test of “tactical guided missiles” on January 17, according to state media outlet KCNA.

These tests were followed by a test of cruise missiles on January 25, and another test of unspecified projectiles on January 27.

North Korea is prohibited from developing nuclear and ballistic missiles by international law, but is not prohibited from testing cruise missiles.

However, Pyongyang has been ramping up testing of ballistic missiles, a move that many believe is aimed at coercing the Joe Biden administration into resuming long-stalled nuclear talks. The US, has not relented, however, and has responded by imposing sanctions on North Korean officials.
