"Greece will not send Patriot defense systems to Ukraine," Greek Prime Minister Kyriakos Mitsotakis said in an interview with Skai TV on Thursday night.
"We were asked and we explained why we can't do it," Mitsotakis said, adding that these systems are "critical to the deterrent capability of Greece's defense."
Reuters writes that defense is a very sensitive issue for Athens given the tensions with Turkey and especially when a conservative government is in power.
Greece has sent thousands of rockets, explosives, IVF vehicles, high-explosive fuzes, ammunition and anti-tank missiles to Ukraine in the past.
The US will host a virtual meeting of international aid donors to Ukraine on Friday, days after Congress broke a half-year gridlock to approve a $61 billion aid package for Ukraine.
On Monday, European Union ministers asked Greece and Spain to provide more air defense to Ukraine, specifically Patriot air defense systems.
