The border between North and South Korea

Every year US and South Korean forces hold joint military drills to prepare for an attack from North Korea.

North Korea views them as a rehearsal for an invasion.

This year's drills begin on Monday.

The BBC's Yogita Limaye has visited the border to talk to the European observers monitoring the ceasefire.
