Tough talk and tension from North Korea
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.

Journalists wait for South Korean employees to return from the KIC after North Korea blocked access to the joint factory zone, a few days before its effective closure was announced. The move shut off one of the North's few sources of hard cash.

Recent threats against South Korea and the United States appear to be aimed partly at boosting internal support for Kim Jong-un (left), the third in his family to lead the reclusive North Korea.
South Korean military vehicles travel during a drill as it snows in Hwacheon, about 20 km (12 miles) south of the demilitarised zone. The same day, North Korea intensified its threats of war, warning foreigners to evacuate South Korea to avoid being dragged into "thermonuclear war".

North Korea's official Flickr and Twitter accounts were targeted by hackers on April 4. Some of the pictures in the Flickr account were replaced by a caricature of North Korea's leader Kim Jong-un as "Pigsy" from the classic Chinese novel "Journey to the West", seen in this photo illustration taken in Singapore.

Portraits of North Korea's founder Kim Il-sung (left) and his son and late leader Kim Jong-il hang on the wall of a mock North Korean classroom at a South Korean observation post, just south of the demilitarised zone. In the next few days, North Korea will observe the 20th anniversary of rule by Kim Jong-il, and the birthday of state founder Kim Il-Sung, occasions which could be pretexts for military displays.
