An Airbus A310-300 from Yemen with 153 people on board has crashed in the Indian Ocean off the island nation of Comoros, aviation officials said. The jet was en route to Moroni, the capital of Comoros, from Yemen's capital Sanaa when it crashed about an hour before reaching its destination, officials said. The cause of the crash has not been determined. It is the second Airbus to plunge into the sea this month. An Air France Airbus A330-200 crashed into the Atlantic Ocean killing 228 people on board on June 1.
