Twenty-four people, among them seven children, were killed on Sunday after their airplane crashed in a river in Brazil. Four people survived the crash, including a 9-year-old boy. The aircraft, which was a twin-engine Embraer turboprop chartered by Manaus Aerotaxis, was carrying 26 passengers and two crew members when it crashed. The pilots of the plane, which had departed from Coari, had supposedly contacted the air traffic control near their destination of Manaus to announce that they were turning back. The plane, however, then disappeared from radar. The plane made an emergency landing in the river Manacapuru, a branch the Amazon river in the Brazilian state of Amazonas, 50 miles (80 kilometers) from Manaus.

A 15ft (4.5 meter) northern bottle-nosed whale has been spotted swimming in the river Thames in Central London, UK. The "Thames whale" managed to swim up past the Thames barrier and under many bridges, reaching as far as Chelsea before it turned around just before Albert Bridge. TV news helicopters scrambled to provide live TV footage of the whale, and many spectators lined the banks of the river. The whale is said to be looking healthy, although some fear that the whale may beach itself as it tried to do before rescuers forced it back into the middle of the river. Normally found in the North Atlantic, there have been sightings of a second whale near Southend.
