SEOUL (BNS): North Korea has deployed a new submarine during naval drills near its bases off the East Sea and Yellow Sea.

According to a Yonhap report, North Korea is carrying out naval exercise by mobilizing five to six submarines, including a new Sango class submarine.

The North recently put the new 40-meter-long Sango submarines into service in addition to its 35-meter-long Sango class submarines, the report said.

Tension has remained high between North Korea and South Korea following the North's two deadly military attacks last year in which 50 South Koreans were killed.

Reports said the South is strengthening its military near the sea borders with North Korea to counter any possible attacks from there.
