"Free Palestine," the protesters chanted as they waved a massive Palestinian flag making their way down Manhattan to Times Square, where the crowd grew larger. Shutting down traffic, the activists took turns addressing the public.

Hosted by NYC Students for Justice in Palestine as part of NY4Palestine wider movement, the crowd condemned Israel's aggression in the recent violence recently on the rise across Israel, the West Bank and Gaza.

Even some Jewish activists joined the rally in support of the Palestinian cause and in protest to PM Benjamin Netanyahu's policies.

Tensions were on the rise at Times Square as Palestinian activists were met by a pro-Israeli rally that also assembled at the center of Manhattan.

The pro Israel supporters condemned the harassment of Palestinian youth of Israeli settlers and the increase of stabbings and attacks on the Jews in Israel.

No major accident were reported between the opposing camps.

Organized by the Coalition for Justice in Palestine, activists rallied downtown near Congress and Michigan Avenue as they too demanded an end to Israeli aggression and occupation.

The protesters also spoke out against their taxes being used by the US government to support the state of Israel. They have also urged the onlookers to boycott Israel and hold it responsible for what they say are numerous violations of human rights.

According to Gaza strip authorities, 43 Palestinians have been killed since the conflict began last month, and over 1,700 have been injured.
