 An extremely dangerous Category 4 storm is moving through the Caribbean with wind speeds of more than 200 km an hour. Reports from the tiny island of Kariakou say it's being flattened by Hurricane Beryl. Reports from the east of the Democratic Republic of Congo say an aid convoy has been attacked in North Kivu province, the scene of recent advances by M23 rebels. The British charity Tearfund said two of its staff were missing.
