North Korea is urging its people to hunker down and work harder with a "70-day campaign of loyalty" before a major meeting of its ruling Workers' Party in May.

Red placards went up around the capital Tuesday starting the campaign. Thousands of Pyongyang residents went to Kim Il Sung Square on Thursday afternoon to show their commitment to the drive.

While the U.N. Security Council is closer to putting new sanctions on North Korea for its recent nuclear test and satellite launch, the North's government has focused internally on a traditional socialist struggle to produce more in the workplace and demonstrate loyalty.
