North Korea fired a short-range missile into the sea off its east coast, South Korea’s military said on Tuesday.

According to Anadolu Agencdy, South Korea’s Joint Chiefs of Staff (JCS) said the missile was fired eastward from North Korea’s Jagang province at around 6:40 a.m. (2140GMT), Yonhap News Agency reported.

South Korean and US intelligence “are analyzing the launch for additional information,” it added.

Top security officials in Seoul met for an emergency meeting after the last missile launch and “voiced regret” over Pyongyang’s move, the report said.

President Moon Jae-in has ordered a “comprehensive analysis” of the missile launch and recent statements from North Korea, the agency quoted his office as saying.

Tensions have been high on the Korean Peninsula after both Pyongyang and Seoul test-launched ballistic missiles just hours apart earlier this month.

The sudden escalation came as the already fraught relations between the neighbors were further strained by the joint US and South Korean military drills in August.

However, Kim Yo Jong, sister of North Korean leader Kim Jong Un, said last week that North Korea could agree to the South’s suggestion to declare a formal end to the Korean War if Seoul drops its “double standards and hostile attitude.”
