Portugal has suspended the issuance of entry visas for Iranian nationals for unspecified security reasons, Foreign Minister Augusto Santos Silva told a parliamentary committee on Thursday. Answering a question from a committee member on whether such move had been taken, Santos Silva said during the televised meeting: 'Yes, we suspended those for security reasons ... I will provide explanations later, but not publicly.' The chairman declared the meeting closed after about two hours without further off-camera testimony. Foreign ministry officials had no immediate and nobody was available for comment in the Iranian embassy in Lisbon.
