Korea Summit Delayed Over Floods

North Korea has asked for a historic summit with the South to be postponed because of severe flooding which may have made 300,000 people homeless. The meeting in Pyongyang, now delayed until October, will be only the second between the leaders of the two states, which technically are still at war. North Korea has made a rare appeal for international aid to tackle the floods which have killed hundreds of people. Damage to farmland could deal a serious blow to this year's harvest.
