German police advised travelers on Sunday (November 5) to avoid Hamburg Airport as a hostage situation is underway.

As a result, the city airport has been closed to passengers and flights canceled since Saturday night (November 4) when an armed 35-year-old man broke through an airport gate with his vehicle and fired two shots into the air, German news agency DPA reported.

Aside from a gun, the man was also allegedly in possession of explosive devices inside the car.

Inside the car with him was his four-year-old daughter, whom he had reportedly taken by force from the mother in a possible child custody battle.
