Tensions between North Korea and the US have escalated rapidly after a US Navy strike group was deployed towards the Korean peninsula in a show of military force.
It comes after Donald Trump discussed North Korea with the Chinese President in Florida and ordered the bombing of a Syrian airbase last week.
After North Korea warned that its military is prepared to defend the nation, here are the latest warnings and live updates on the situation.
Wednesday 03:42 BST: North Korea should halt any plans for nuclear and missile activities "for its own security", a Chinese newspaper said on Wednesday, warning that the United States is making clear it doesn't plan to "co-exist" with a nuclear-armed Pyongyang.
03:35am BST: The Japanese Maritime Self Defence Force (MSDF) may carry out helicopter landings on the USS Carl Vinson, which was deployed near the Korean peninsula in the wake of Kim Jong-un’s missile tests.
It is believed the joint military drills are to be carried out as a show of strength towards Kim Jong-un’s regime.
An anonymous source told Reuters: "Japan wants to dispatch several destroyers as the Carl Vinson enters the East China Sea."
One source who told Reuters about the drills has direct knowledge of the plan, while the other has reportedly been briefed.

Mr Spicer further said Mr Trump was keeping his options on the table but any direct response to North Korea would be “decisive and proportional”.

Pyongyang has slammed ‘reckless moves’ by the US and pledged to defend the North Korea from invasion ‘by powerful force of arms’, according to state media.
A Foreign Ministry spokesman was quoted as saying: “We will hold the US wholly accountable for the catastrophic consequences to be entailed by its outrageous actions.”
But China and South Korea have agreed to slap tougher sanctions on North Korea if the country carries out nuclear or long-range missile tests, according to an official in Seoul.
Former MI6 head Sir John Sawers has warned that tensions with North Korea are actually a much bigger threat to world peace than the war in Syria.
“If you are looking for a world crisis which could bring about the dangers of a clash between great powers then North Korea is a bigger concern than Syria,” he told BBC Four’s Today programme.
At the weekend, Secretary of State Rex Tillerson said Donald Trump and Xi Jinping had “extensive discussions around the dangerous situation in North Korea” at a summit at in Florida last week.
“President Xi clearly understands, and I think agrees, that the situation has intensified and has reached a certain level of threat that action has to be taken,” he told CBS’s Face the Nation.
