Turkish President Recep Tayyip Erdogan reportedly defended Hamas on Monday, claiming that more than 1,000 members of the terrorist group from Gaza are being treated at hospitals in his NATO nation.

At a joint press conference in Ankara, Turkey, Erdogan took issue with Greek Prime Minister Kyriakos Mitsotakis having categorized Hamas as a “terrorist organization.”

“If you call Hamas a ‘terrorist organization,’ this would sadden us,” Erdogan said, according to Reuters.

“We don’t deem Hamas a terrorist organization,” he reportedly said. “More than 1,000 members of Hamas are under treatment in hospitals across our country.”

The press conference followed a two-hour face-to-face summit with the Greek prime minister.
