Şırnak deputy of pro-Kurdish People’s Democracy Party (HDP) Ferhat Encü announced on Thursday that his passport was confiscated at İstanbul airport as he was getting ready to board on plane for a flight to Brussels.

Encü wrote on Twitter that due to a travel ban abroad issued by a court on Thursday, he was not able to leave Turkey.

The travel ban on HDP deputy followed the increasing pressure on Kurdish politicians as the co-mayors of Diyarbakır were arrested on October 31.

Turkish government has been cancelling passports of critics in mass numbers especially since the failed coup of July 15. The Ministry of Interior Affairs has revoked over 50 thousand passports according to a post-coup statement, but the exact figures are unknown.

Many journalists and academics in Turkey are also banned from travelling abroad even when their passports are not revoked.
