Greece announced today, Friday, an increase in alert status following a warning of an imminent targeting of Israeli interests on its territory. In detail, Greece has placed the national intelligence service and anti-terrorism authorities on high alert after receiving a warning in Athens from foreign security agencies about a potential attempt to strike an Israeli interest in Greece, according to the German news agency. These latest developments came after the assassination of the head of the political bureau of Hamas, Ismail Haniyeh, which raised concerns about possible retaliatory attacks in third countries, as reported by the Greek newspaper Kathimerini today, Friday.
