As European countries like France raised terror alert levels after the attack on Moscow, Germany's interior minister said border security will be bolstered ahead of this summer's European Championship.

Germany will introduce temporary controls at all its borders for the European Championship this summer, Interior Minister Nancy Faeser told the Rheinische Post newspaper on Tuesday.

The measures come in the wake of the terror attack in Moscow on Friday.

"We will carry out temporary border controls at all German borders during the tournament in order to prevent possible perpetrators of violence from entering the country," Faeser told the newspaper.

"This is necessary to provide the best possible protection for this major international event," added the minister. 

German Chancellor Olaf Scholz said the temporary checks were a "proven set of instruments" for security. Scholz told reporters during a visit to Slovenia that security has always been a "top priority." The checks were not unusual, he said.

Faeser said border control would focus on the threat of Islamist terrorism, extremists, hooligans and other violent criminals. Measures will also include network security against cyberattacks.

Faeser explained that the threat of Islamist terror was already high before the current attack and remains so now. 

Germany, however, does not issue terror alert levels like other countries do.
