Reporting from Jerusalem — — Israeli naval ships seized control of a protest flotilla carrying humanitarian aid to the Gaza Strip on Monday, killing at least 10 people and sparking widespread international condemnation.
Israeli television, citing foreign media reports, said the death toll could be as high as 16.
"The images are certainly not pleasant. I can only voice regret at all the fatalities," Trade and Industry Minister Binyamin Ben-Eliezer told Israel's Army Radio.
The raid set off a storm of international protest and drew condemnations from leaders of Spain, Sweden, France, Germany, the U.N., the European Union and Arab League.
But after some initial expressions of regret, Israeli officials Monday came out strongly in defense of the raid, characterizing the protesters as hard-core extremists who had prepared an ambush for soldiers.
Deputy Foreign Minister Danny Ayalon called the flotilla an "armada of hate and violence" that launched a "premeditated and outrageous provocation." He said Israeli soldiers found evidence that "weapons" had been prepared in advance, but he did not specify whether those weapons included guns.
Israel's military said protesters managed to grab two guns from Israeli soldiers and use them against the commandos, prompting soldiers to return fire.
Greta Berlin, leader of Free Gaza, one of the flotilla's organizers, called those claims "absurd."
"This was murder," Berlin said in a telephone interview from Cyprus.
The six-vessel flotilla, packed with hundreds of international activists, food and other humanitarian supplies, had left Cyprus on Sunday night in an attempt to break Israel's longstanding blockade of the Gaza Strip.
Israel had vowed to intercept the boats, by force if necessary, and tow them to the Israeli port of Ashdod, where passengers would be arrested or deported.
According to an Israeli commando, speaking on condition of anonymity, he and other Israeli soldiers who rappelled onto a boat from a helicopter were immediately attacked by about 30 people on board.
"They beat us up with metal sticks and knives," he said. "There was live fire at some point against us. ... They were shooting at us from below deck."
He said activists tossed some of the soldiers from the top deck to the lower deck and the soldiers jumped in the water to save themselves. Activists grabbed some soldiers and tried to hold them hostage, stripping them of their helmets and equipment, he said.
Ten Israeli soldiers were wounded, two seriously, the military said.
Protest organizers said the nighttime raid on the Turkish-flagged Mavi Marmara, the flotilla's largest vessel with 600 passengers, occurred in international waters more than 40 miles off shore.
Video released by television crews onboard and a live Internet signal transmitted from the boat show armed and masked Israeli soldiers rappelling from helicopters onto the boat and being attacked by passengers with iron clubs.
Berlin said the activists were acting in self-defense after soldiers opened fire.
"People had the right to defend themselves against soldiers armed with machine guns,'' she said in a telephone interview from Cyprus. The group had been unable to reach passengers since the attack occurred because the Israeli military had blocked telephone signals, she said. "They can spin it any way they want. We're the civilians, and they are the military."
According to Berlin, flotilla organizers hoped to bring international attention to Israel's Gaza blockade and expected a confrontation, "but we never expected this kind of violence."
The group had launched nine previous ships to Gaza, and five were permitted to pass to the territory after being searched by the Israeli navy.
Protest organizers described a chaotic early-morning takeover in international waters.
Berlin earlier told Israel Radio that the confrontation was broadcast live from a Turkish boat participating in the flotilla. The footage, she said, clearly showed Israeli soldiers opening fire on civilians.
"The minute their feet hit the deck, they started to shoot," Berlin said.
She added, "Something happened to your country to make it think it is all right" to shoot civilians.
Israel Defense Force sources told Ynet, a popular Hebrew-language website, that the "organizers were not innocent — they demonstrated violence against the soldiers. They were prepared for their arrival."
Israeli radio military analyst Yoav Limor blamed the military for underestimating the resistance it would encounter. "There was serious violence" that forced the soldiers to open fire, he said.
But condemnation was wide and swift.
Protests against Israeli embassies in Jordan and Turkey erupted, and Greece canceled a planned joint military training exercise in protest.
