Hundreds of angry protesters gathered in Iran's capital Tehran on Friday to stage demonstrations in solidarity with Palestinians and to denounce Israel and the United States in the wake of a series of deadly protests in the Gaza Strip territory, an epa-efe photojournalist at the scene reported.

Placards with slogans threatening to wipe out Israel and chants of "down with USA" belied the atmosphere of the protest staged by supporters of the Islamic Republic of Iran's leaders, for whom Israel and the US are traditional foes.

Tensions between regional powers Iran and Israel and Israel's main international ally Washington rose again Monday when members of the Israeli military decided to open live fire on a large gathering of protesters who had gathered by the buffer zone that runs along the Gaza Strip enclave, killing 62 people and injuring another 2,500.

The demonstrations occurred just before Nakba Day, or the Day of Catastrophe, which is marked each year on May 15, the day following Israel's Independence Day, to commemorate the mass expulsion of over 700,000 Palestinians both before and after the founding of the state of Israel in 1948.

The day of action had been called for to oppose the United States' decision to move its embassy to Jerusalem, a city it has since recognized as the capital of Israel.

The United Nations estimates that, of the Gaza Strip's nearly 2 million inhabitants, two out of every three are refugees or their descendants.
