Pro-Palestinian protesters in New York hung a massive Palestinian flag emblazoned with the words “Boycott, Divest, Sanctions” from the Manhattan Bridge as protesters marched across the nearby Brooklyn Bridge during a demonstration against Israeli military action in Gaza Wednesday.

The flag was unfurled during a protest that organizers said was meant to “connect the struggle of the Palestinian population to those of oppressed communities throughout the US,” referring to the situation in Ferguson, Missouri, following the shooting of an unarmed black teenager by local police.

Police removed the flag and said they were investigating the incident.

However, New York City Councilman David Greenfield blasted the police department in a series of tweets for not taking measures to prevent the incident.

Prior to the demonstration protesters planned to “cover the Brooklyn Bridge in a ‘sea of Palestinian flags’ to show NYC’s support for Palestine and resistance to Israeli’s campaign of aggression, occupation, and ethnic cleansing,” the organizers said in a press release.

Several hundred people were reported to have participated in the protest.

Wednesday’s protest was the latest of many worldwide against Israel’s military action in Gaza during Operation Protective Edge. Tens of thousands have taken part in such demonstrations across the US, the United Kingdom, Turkey, Germany, France and elsewhere, many of which have taken on tones of anti-Semitism.

Over 2,000 people have been killed in Gaza in the past month’s fighting, Hamas sources say. Israel says 750-1,000 of the dead are Hamas and other gunmen. It also holds Hamas responsible for all civilian casualties due to its tactics of firing from within populated areas and using human shields. Israel has lost 64 soldiers and three civilians in the fighting. Eleven of the soldiers were killed by Hamas gunmen emerging from cross-border tunnels dug under the Israeli border. Hamas has fired some 3,500 rockets at Israel, including some 600 from close to schools, mosques and other civilian facilities, the Israeli army says.
