North Korea has fired an unidentified projectile, the South's military says, less than a week after its leader Kim Jong Un oversaw the test-firing of multiple rockets and a missile.

The projectile was fired at about 4.30pm (0730 GMT) from the northwest town of Sino-ri, in an easterly direction, the South's Joint Chiefs of Staff said in a statement. The Joint Chiefs of Staff did not immediately release further details.
A South Korean official, who spoke on condition of anonymity, said the projectile was believed to have flown around 420km.
"You don't know what missile it is just from how far it flew," said Yang Uk, senior research fellow at the Korea Defence and Security Forum.
"But one thing is clear - there's no doubt that it is a missile."
Such a range would likely be longer than most of the weapons launched on Saturday, when North Korea fired a number of rockets from its east coast into the ocean, sharply raising tension on the Korean peninsula at a time of stalemate in talks between North Korea and the United States.
However, on Saturday, North Korea also launched at least one short-range ballistic missile, which analysts said could reach up to 500km.

On Wednesday, North Korea lashed out at the United States and South Korea, saying its tests on Saturday were "regular and self-defensive" and rejecting the notion that they were provocative.
South Korea responded to Saturday's action by the North by calling for an end to acts that escalate military tension.
A spokeswoman for South Korea's presidential Blue House said President Moon Jae-in's national security adviser, Chung Eui-yong, was closely monitoring the situation on Thursday through a video conference with the military.
Japan's defence ministry said it had not detected any ballistic missile in Japanese territorial waters or exclusive economic zone and it saw no direct impact on Japan's security.
Escalation tactics
The area where today's projectile was launched was identified as the site of a medium-range Rodong missile base on North Korea's west coast, by the Centre for Strategic International Studies, a Washington-based think tank.
Saturday's launch of a short-range missile from an east coast area was the North's first test of a ballistic missile since it launched an intercontinental ballistic missile in November 2017.
At the end of 2017, North Korean leader Kim declared its nuclear force was complete and extended an olive branch to the South and the United States, holding two summit meetings with US President Donald Trump and three with the South Korean leader.
But Mr Kim's second summit with Mr Trump, in Vietnam in February, broke down with the United States insisting the North give up its nuclear programme and North Korea seeking sanctions relief.
"North Korea has returned to its classic escalation tactics from before," Mr Yang said. "I believe they will keep escalating by using what appear to be short-range missiles, something that will not cause the US to react right away."

The launch came as US special envoy for North Korea Stephen Biegun was in Seoul for talks with South Korean officials. Mr Biegun has meetings with Foreign Minister Kang Kyung-wha as well as his counterpart, South Korea's nuclear envoy Lee Do-hoon.
