The order was handed to the Bangladeshi clerics who run the mosque in Venice’s most populated neighbourhood, informing them that its activity did not comply with its official use.
The Kosovar jihadists, who resided in central Venice, were arrested last month after a probe in which they were taped allegedly saying it would be easy to find paradise by bombing Venice "because of all the Christians here".
The trio’s arrest followed 12 raids carried out on homes in the area, including 10 in Venice's historic centre, one in Mestre and one in Treviso to the north.
