Demonstrators took to the streets of San Francisco Memorial Day to protest a deadly Israeli commando raid on ships taking aid to the blockaded Gaza Strip.
About 200 protesters gathered Monday afternoon in front of the Israeli consulate in downtown San Francisco to condemn the raid before marching through the city.
Protest organizers said four San Francisco Bay area activists aboard the ships were unharmed.
A few dozen counter-protesters waving Israeli and American flags confronted pro-Palestinian demonstrators, but police kept the groups apart.
A small group tried to block San Francisco's historic cable cars but were moved away by police. No arrests were reported.
Also Monday, the international fallout grew over Israel's deadly raid.
Nine passengers were killed in the raid. Most were apparently from Turkey, which has now withdrawn its ambassador to Israel. Turkey is also calling for an emergency session of the U.N. Security Council.
In Istanbul, a crowd tried to storm the Israeli Consulate. North of Jerusalem, Palestinians hurled bottles and stones at Israeli soldiers. In Jordan, hundreds urged their government to follow Turkey's lead and cut ties with Israel.
In Iran's capital, dozens of angry students pelted U.N. offices with stones and eggs.
Riot police using tear gas drove back hundreds of protesters outside the Israeli Embassy in Paris. The demonstrations there -- and in Rome, Sweden, Norway and elsewhere -- are among the protests being seen across Europe.
Greece, Egypt, Sweden, Spain and Denmark summoned Israel's ambassadors demanding explanations, with Spain and France condemning what they called the disproportionate use of force.
