The German air force says two fighter jets have collided in the northeast of the country, but the pilots were able to eject.
Local radio station Ostseewelle reported that the two Eurofighter jets collided shortly before 2 p.m. (1200 GMT) Monday near Lake Mueritz, about 100 kilometers (62 miles) north of Berlin.
A spokeswoman for the interior ministry of the eastern state of Mecklenburg-Vorpommern said: "I can confirm that there was an accident involving two aircraft in northern Germany."
A video posted online shortly after the crash showed two plumes of smoke rising from the ground.
The Schweriner Volkszeitung daily reported that falling wreckage caused forest fires and may also have hit inhabited areas.
