South Korea's Red Cross said today it would send 5,000 tons of rice in aid to flood-stricken North Korea, in the latest sign of improving relations after months of high tensions. The Red Cross said it would also ship 10,000 tons of cement to help rebuild flood-damaged homes plus three million packs of instant noodles.Cross-border relations have been icy since Seoul accused Pyongyang of torpedoing of one its warships in March, killing 46 people. The North denies the charge. But last week the North freed a South Korean fishing boat crew seized for illegal fishing, and offered to hold a new round of reunions for families separated by the peninsula's division.
