PRAGUE (Sputnik) — According to Zeman, the country's intelligence services provide a lot of information about such possibility making security measures hard to discount.
"Yes, naturally, we are the next," Zeman said, as broadcast by local TV Blesk, answering a question concerning possible terrorist attacks in the Czech Republic.
"I personally had reinforced Prague Castle even before Berlin attack," Zeman said.
The Czech authorities installed walk-through metal detectors at the entrance to the Prague castle which is the official residence of the Czech president in August 2016.
