ISTANBUL, May 31 (Xinhua) -- Two Turkish supporters were killed and 30 others injured as Israeli ships attacked one of the six ships of a relief flotilla carrying humanitarian aid for Gaza early Monday.
IHH, a Turkish humanitarian relief organization which carries out the aid campaign, said in a statement posted on its web-site that Israeli troops boarded the ship from a helicopter and opened fire.
Meanwhile, Turkey's Ministry of Foreign Affairs will summon Israeli ambassador in Ankara Gaby Levi later in the day.
Turkish Foreign Minister Ahmet Davutoglu, who is on his way from Brazil to the United States, informed Turkish President Abdullah Gul and Prime Minister Recep Tayyip Erdogan on the developments.
Mehmet Kaplan, a Swedish parliamentarian of Turkish descent, is also on board one of the ships in the flotilla.
After Israeli ships attacked the aid convoy, a crowded group of protestors gathered in front of the Israeli Consulate General in Istanbul. They protested the attack by chanting slogans.
Tight security measures have been taken around the consulate building.
The flotilla, which includes three cargo ships and three passenger ships, is trying to draw attention to Israel's three- year blockade of the Gaza Strip. The boats are carrying items such as electric-powered wheelchairs, prefabricated homes and water purifiers.
