Athens, Greece – The Greek government has issued travel backpack restrictions for tourists visiting the country after a string of deadly terror attacks in Europe.

Greece is on the list of destinations that will be checked for passengers travelling on passports issued by the International Civil Aviation Organization.

The restrictions are expected to be in place from Monday, the Greek Tourism Ministry said.

The ministry has also restricted the availability of travel tickets, hotel reservations, and accommodation in some areas, and issued a warning to travelers in Greece.

A travel ban on all Greek tourists, including those travelling from the country, has been imposed by the Greek government, according to the ministry.

More than 500 people have been killed in the attacks, which have been blamed on a new strain of Islamic State group.

The terror group has claimed responsibility for most of the attacks.

In the latest attacks, an Italian tourist, a Serbian man and a Belgian woman were killed in a suicide attack at a beach resort in the southern Italian town of Reggio Emilia, the ministry said.

The second attack occurred in the town of Sint Maarten, where a Tunisian man was killed and five others injured when a suicide bomber detonated his explosives-laden truck, according the ministry, which is not a state agency.

The Greek government is now considering the introduction of measures to tighten security measures in the country.

“We are monitoring developments and we are taking measures to ensure that Greece remains safe,” said the Greek Ministry of Foreign Affairs in a statement on Sunday.

The new restrictions come as Athens prepares to host the EU and NATO summit in September.
