North Korea has tested several short-range missiles, according to reports from South Korea.

They were fired from the Hodo peninsula in the east of the country, said South Korea's Joint Chiefs of Staff.

If confirmed, it will be the first missile launch since Pyongyang tested an intercontinental ballistic missile in November 2017.

Last month Pyongyang said it had tested what it described as a new "tactical guided weapon".

That was the first test since the Vietnam summit between the North Korean leader, Kim Jong-un, and US President Donald Trump, which ended without agreement.

President Trump walked away from what he described as a bad deal offered by Kim Jong-un in Hanoi in February.

Firing a short range missile would not violate North Korea's promise not to test long range or nuclear missiles.

But Pyongyang appears to be growing impatient with Washington's insistence that full economic sanctions remain until Mr Kim takes serious steps to dismantle his nuclear weapons programme, says the BBC's Laura Bicker.

"We are aware of North Korea's actions tonight," said White House spokeswoman Sarah Sanders. "We will continue to monitor as necessary."

North Korea "fired a number of short-range missiles from its Hodo peninsula near the east coast town of Wonsan to the north-eastern direction from 09:06 (00:06 GMT) to 09:27," the South's Joint Chiefs of Staff said in a statement.
