Bosnian police said Friday they have arrested five men suspected of building an explosive device intended for a terrorist attack in an unspecified Scandinavian country.

Three of the arrested were nabbed at the border while trying to leave Bosnia with the explosive device in the trunk of their car, while the two others were arrested in Sarajevo.

The arrests were the result of a coordinated operation also involving officials from Netherlands and Sweden.

The five suspects, including one Swedish and four Bosnian nationals, are suspected of having built the bomb in Bosnia after receiving "a request" from Scandinavia.

In recent months Bosnia have arrested a few dozen people suspected of links to global terrorism, including many for fighting in Syria and Iraq or for recruiting and funding other Balkan men to join the Islamic militants there.
