South Korean and U.S. forces began live-fire exercises simulating a "full-scale attack" from North Korea on Thursday in what they said were the biggest such drills to demonstrate their "overwhelming" military capability against the North's threats.
Howitzers pounded into a mountainside in Pocheon near the fortified border with North Korea, while battle tanks manoeuvred and fired their guns at targets, sending smoke, dust and shockwaves across the valley.
