Turkey's prime minister on Tuesday said Israel's raid on a Gaza-bound Turkish aid vessel that killed several people was a "bloody massacre".
Recep Tayyip Erdoğan said in Parliament that "no one should test Turkey's patience".
Israeli commandos on Monday killed several pro-Palestinian activists after raiding humanitarian aid ships that were en route to the Gaza Strip. The largest ship in the flotilla was the Turkish Mavi Marmara, with around 600 people on board.
