Excerpt:
Italy has deported five members of the same family "for reasons of national security", interior minister Angelino Alfano announced on Sunday.
Alfano said he had ordered the expulsions after a "long and complex investigation" into a Facebook account which had posted "countless" videos and documents in support of the terrorist group Isis.
Police identified the owner of the account as a 28-year-old Macedonian living in Gorizia, northeastern Italy.
The man's two brothers-in-law, aged 31 and 28, along with their 52-year-old father and one of the brothers' wives, aged 32, were also expelled on Sunday for posting numerous extremist messages on social media sites.
