Spain has raised its terror threat level following the attack on a French satirical newspaper that killed 12 people, but the country's interior minister says there is no intelligence indicating the nation faces imminent danger.

Jorge Fernando Diaz says the threat level was raised from Level 2 to Level 3, with five being the highest on the scale. The move means that authorities will increase security measures at key infrastructure installations, but Fernando Diaz didn't specify which ones.

He says Spain last used the terror Level 3 measure in June for nine days when the country prepared for the coronation of King Felipe VI.

In 2004, bombs on rush-hour trains killed 191 people in Madrid in Europe's worst Islamic terror attack.
