Seoul resumes psychological warfare with Pyongyang

Tensions on the Korean peninsula soared Tuesday as South Korea resumed propaganda broadcasts into North Korea in retaliation for the deadly sinking of a warship, while the North's leader reportedly has ordered troops ready for combat.

The South's restarting of psychological warfare operations was among measures it announced Monday, along with slashing trade, to punish Pyongyang for the March torpedo strike that sank a navy warship and killed 46 sailors. The US has thrown its full support behind South Korea's moves to retaliate, which also include bringing North Korea before the UN Security Council. (AP)
