North Korea has fired at least one "unidentified projectile" towards the sea of Japan on Thursday, read a statement from South Korea's Joint Chiefs of Staff (JSC).
"North Korea fired two unidentified projectiles toward the East Sea (the Sea of Japan)," the JSC statement read.
JSC said the "projectiles were fired from areas in South Pyongan Province in the afternoon," adding that, "Our military is monitoring the situation in case of additional launches and maintaining a readiness posture."
No details were given on the projectiles' type and or flight range.
The Japan Coast Guard has requested all vessels operating in the Sea of Japan to remain alert and monitor news channels.

Thursday's missile test comes after North Korea said on Oct. 03 that it test-fired a new type of submarine-launched ballistic missile.
"The new-type ballistic missile was fired in vertical mode," State-run Korea Central News Agency (KCNA) reported earlier this month. "The test-firing scientifically and technically confirmed the key tactical and technical indexes of the newly-designed ballistic missile and had no adverse impact on the security of neighboring countries."
Earlier this week, North Korea said it's becoming impatient with Washington over the stalled nuclear talks.
The rogue nation has set a year-end deadline for possible denuclearization of the Korean Peninsula.
North Korean general Kim Yong Chol recently said there had been zero progress in U.S.-North Korea relations. He added that Washington would be "seriously mistaken" to overlook a year-end deadline to find mutual terms for a possible future denuclearization deal.
North Korea has said the missile tests have been necessary to defend the country against Washington and its allies surrounding it with fifth-generation fighter jets.
