Five people were killed and about 200 injured when a man drove his car into a Christmas market in Germany on Friday.
A 50-year-old Saudi doctor was arrested after the incident in which he ploughed into people attending a busy night market in the Saxony-Anhalt state capital of Magdeburg in the central north of the country, killing four women and a nine-year-old boy.
The motives of the man, who had lived in Germany for two decades, was unclear but media reports suggested the incident stirred up simmering tension over immigration.
Also on Friday, 38 people died and 100 were missing after a ferry capsized on the Busira River in the north-east of the Democratic Republic of the Congo.
The incident, involving a vessel overloaded with people returning home for Christmas in the central African country, came less than four days after another boat capsized in the country’s north-east, killing 25 people.
Ferries are an important form of transport in the Congo due its extensive river network and poor road infrastructure but accidents occur regularly.
Meanwhile in Brazil on Saturday, at least 38 people were killed when a bus and truck collided in the state of Minas Gerais.
Officials said the bus burst into flames after blowing a tyre, causing the driver to lose control and crash into a lorry.
A car also collided with the bus but the passengers survived.
A day later, two U.S. Navy pilots survived after their aircraft was accidently shot down over the Red Sea in an apparent "friendly fire" incident.
Both pilots ejected from the aircraft and were rescued with one suffering minor injuries.
