Trump warns North Korea, of fire and fury like the world has never seen

The U-S and North Korea have traded escalating threats, after reports that Pyongyang has mastered a crucial technology needed to strike America with a nuclear missile.
 President Donald Trump warned of ``fire and fury like the world has never seen,'' while Pyongyang said it was examining plans for attacking the U-S island territory of Guam.
The competing threats have heightened worries that a miscalculation might spark a major conflict.
Reports published Tuesday indicate the North can now attach nuclear warheads to its long-range missiles.
