PRAGUE, Dec. 19 (Xinhua) -- Czech police will tighten security measures after at least nine people were killed on Monday in Berlin when a lorry ploughed into the crowd, Czech Interior Minister Milan Chovanec announced.
The decision was made after a discussion with Czech Police President Tomas Tuhy, Chovanec wrote on his twitter account.
The number of police patrols on streets will rise by Tuesday and authorities will meet, probably on Tuesday morning, to decide whether to raise the level of terrorist threat in the Czech Republic, Chovanec told Czech Television (CT).
According to the official, based on the information gathered so far, an upgrade of terrorist threat level in the country is unnecessary.
A lorry ploughed into a crowd at a Christmas market in Berlin on Monday night, killing nine people and injuring 50 others, Berlin police have announced.
