Israel has denied Turkey’s request to join air drops of humanitarian aid to Palestinians in Gaza, and Ankara will take new measures against Israel in response, its Foreign Minister Hakan Fidan said on Monday.

Turkey, which has denounced Israel for its offensive in the densely populated Gaza Strip and called for an immediate ceasefire, has sent tens of thousands of tons of humanitarian aid there since the start of the Israel-Hamas war on October 7.

The United States started dropping deliveries of aid into Gaza by air last month, with the Netherlands, France, Spain and others contributing.

“We also conveyed our request to be included in this humanitarian aid operation with [Turkish] air forces’ cargo planes. Today we learnt that our request was rejected by Israel, despite a positive approach by the Jordanian authorities,” Fidan said in a statement to the media.

Israeli authorities did not immediately respond to requests for comment.

There is no excuse for Israel to block our attempt to drop aid to starving Gazans,” Fidan said, adding that Turkey has decided to take a “series of new measures” against Israel.

“These measures, approved by our president, will be implemented step by step, without delay,” Fidan said, without elaborating.

“The measures to be announced by our relevant institutions will continue until Israel declares a ceasefire and allows humanitarian aid to reach Gaza without interruption,” he said.
