SEOUL (AFP): South Korea and the United States began annual war games today, US Forces Korea said, amid heated warnings by Pyongyang that the exercises will worsen tensions in the region.

Tens of thousands of troops are taking part in the "Ulchi Freedom Guardian" joint military drills, a largely computer-simulated exercise that runs for two weeks in the South.

They are described as defensive, but nuclear-armed Pyongyang views them as a highly provocative rehearsal for invasion.

The drills come during a standoff on the peninsula since Pyongyang tested two intercontinental ballistic missiles (ICBM) last month that appeared to bring much of the US within range.

That sparked a grim warning by President Donald Trump that Washington could rain "fire and fury" on the North.

Pyongyang threatened to fire a salvo of missiles towards the US territory of Guam - a plan that leader Kim Jong-Un last week delayed, but warned could go ahead depending on Washington's next move.

While the allies are pushing ahead with the exercises that date back to 1976, around 17,500 US troops will participate in the drills - a cutback from last year.

South Korean media reports have said the US was considering scrapping a plan to bring in two aircraft carriers to the peninsula.

But US Defence Secretary James Mattis said on Sunday the smaller troop numbers were "by design to achieve the exercise objectives", denying suggestions Washington had cut them back to try to ease tensions with Pyongyang.

"This right now is an exercise to make certain that we're ready to defend South Korea and our allies over there," Mattis told reporters aboard an aircraft flying to Amman, Jordan.

US Pacific Command chief Admiral Harry Harris arrived in the South on Sunday to inspect the exercises and discuss growing North Korean nuclear and missile threats.

On the eve of the UFG drills, North Korea said the US was "pouring gasoline on fire".

In a commentary carried by the official Rodong Sinmun newspaper, the North warned of an "uncontrollable phase of a nuclear war" on the peninsula.

Washington was "mistaken" to think that such a war would take place on "somebody else's doorstep far away from them across the Pacific", it added.
