Italy’s Defence Minister Guido Crosetto has condemned an overnight drone attack on the Global Sumud Flotilla that is headed to Gaza in an attempt to deliver aid.

In a statement on Wednesday, Crosetto said he redirected an Italian navy ship towards the flotilla to offer it possible assistance. His comments came after the Global Sumud Flotilla reported explosions and communications interference.

Foreign Minister Antonio Tajani said there are “Italian citizens along with members of parliament and MEPs” among the pro-Palestinian activists in the flotilla, which reported hearing more than a dozen nearby blasts as it sailed off Greece late Tuesday.

It also reported damage caused by “unidentified objects” dropped on deck.

“To ensure their safety, the foreign ministry had already notified Israeli authorities that any operation entrusted to Israeli forces must be conducted in compliance with international law and the principle of absolute caution,” it said in a statement.

“Minister Tajani has asked the Italian Embassy in Tel Aviv to gather information and to reiterate its previous request to the Israeli government to guarantee the absolute protection of the personnel on board.”
