Czech President Milos Zeman is under fire after suggesting that the way to get rid of Prime Minister Bohuslav Sobotka would be either democratically in elections or undemocratically with a Kalashnikov rifle.

Zeman was quoted by media as saying that during a public debate in the town of Tisnov Monday

In a joint statement Tuesday, the speakers of both houses of Parliament condemned Zeman's remarks.

Jan Hamacek and Milan Stech said the comments "only damage political culture ... and contribute to the rising tension and hatred in society."

Zeman is known for his anti-Islam rhetoric and called the influx of migrants an "organized invasion."

Sobotka said the remarks were "silly" and frightened his children and other family.
