(CNN) A raft of nations have temporarily suspended Boeing 737 Max flights after the fatal plane crash in Ethiopia but the United States and Canada are still flying a substantial number of those models.

The European Union began suspending Boeing 737 Max flights in Europe on Tuesday, joining more than a dozen nations and aviation authorities that have halted the aircraft's operations all over the world. The move came after a Max 8 flight from Addis Ababa, Ethiopia, to Nairobi, Kenya, crashed Sunday into a field six minutes after takeoff, killing all 157 people on board. The flight reported technical problems and asked for permission to turn back before it crashed, and investigations are underway into the cause.

It's the second time in less than six months that this model has crashed soon after takeoff. A new Lion Air Boeing 737 Max 8 flight went down in October over the Java Sea off Indonesia, killing 189 people.

Multiple countries ground planes

Before the EU's announcement, nations like Australia, Austria, Belgium, France, Germany, Iceland, Ireland, Italy, Malaysia, the Netherlands, Oman, Singapore, Turkey and the United Kingdom announced their own bans on Tuesday.
