South Korean soldiers take part in an artillery drill as part of the annual joint military exercise "Foal Eagle" near the demilitarised zone which separates the two Koreas.
Tensions have been rising on the divided peninsular, and South Korea said on April 10 there was a "very high" probability that North Korea, engaged in weeks of threats of war, would test-launch a medium-range missile at any time as a show of strength.

The North has suspended operations at the joint industrial park, which it operates with South Korean companies. North Korea's official news agency said Seoul was trying to "turn the zone into a hotbed of war".
The decision comes as Pyongyang has dialled up its shrill rhetoric, threatening a nuclear strike on the United States - something it does not have the capacity to carry out - and "war" with South Korea.

Tension has been increasing since the United Nations imposed new sanctions against the North in response to its third test of a nuclear weapon in February. Pyongyang has been further angered by weeks of joint military exercises by South Korean and U.S. forces and threatened both countries with nuclear attack.
But North Korea has shown no sign of preparing its 1.2 million-strong army for war, indicating its recent threats are partly intended for domestic purposes to bolster Kim Jong-un, 30, the third in his family to lead the reclusive country.
