GAZA, May 3 (Xinhua) -- Two Islamic Hamas movement militants were killed on Friday evening in an Israeli army airstrike on a military training facility that belongs to the movement in central Gaza Strip, medics and security sources said.

Ashraf al-Qedra, spokesman of the Health Ministry in Gaza, told reporters that Abdulla Abu Mallouh, 33 years old and Alla Boubali, 29 years old from al-Mughazi refugee camp in central Gaza Strip, were killed in the Israeli airstrike.

Palestinian security sources in Gaza said that Israeli aircrafts struck a military training facility that belongs to Hamas armed wing al-Qassam Brigades in central Gaza Strip, not far from the border between eastern Gaza Strip and Israel.

Meanwhile, an Israeli army spokesman said that the Israeli airstrike on the military training facility of Hamas was a response to an earlier gunfire attack on an Israeli army force, stationed on the border with the Gaza Strip.

The spokesman said that one Israeli soldier was moderately injured and was evacuated to an Israeli hospital for medical treatment, adding that another female soldier was slightly injured in the shooting attack.

Meanwhile, at least 50 Palestinians injured in clashes on Friday between demonstrators who joined the weekly anti-Israel protests and Israeli soldiers stationed on the border between eastern Gaza Strip and Israel, medics said.

At least 50 Palestinian demonstrators were shot and injured by Israeli soldiers' gunfire in eastern Gaza Strip, including 10 children, two women, one journalist and three paramedics.

Eyewitnesses said that the demonstrators waved Palestinian flags, chanted anti-Israel slogans and threw stones at the soldiers in several areas in eastern Gaza Strip close to the border with Israel.

Field paramedics said that the soldiers fired tear gas, rubber bullets and live gunshots at the demonstrators, adding that many of them were injuries and suffered suffocation after inhaling the Israeli tear gas.

Local media sources said that activists of the Great March of Return released several arson balloons from eastern Gaza Strip into southern Israel, while Israeli media reports said that several demonstrators climbed on the fence of the border.

Meanwhile, Palestinian security sources in Gaza said that an Israeli army tank fired at least three tank shells on eastern Gaza Strip targeting military facilities that belong to Islamic Hamas movement and no injuries reported.

The Israeli media reported that the tanks shelling on eastern Gaza Strip was an immediate response to opening fire by Palestinian gunmen at an Israeli army force stationed on the border, adding that one soldier was moderately injured.

The Highest Commission of the Great March of Return and Breaking the Israeli Siege had earlier called on the populations of the Gaza Strip to join the weekly rallies and protests, which started in March 30 last year in eastern Gaza.

The commission said in a statement that the protests on Friday are against the United States' decision to consider the Syrian Golan Heights under Israel's sovereignty.

Gaza Health Ministry said that since the outbreak of the weekly protests, the Israeli army shot dead 273 demonstrators and wounded 17,000 others who were officially referred to the hospitals in the Gaza Strip.

On Thursday, two delegations representing Islamic Hamas movement and the Islamic Jihad headed to Egypt for talks in Cairo with senior Egyptian security intelligence officials on a possible calm with Israel in the Gaza Strip.

Khader Habib, a senior Islamic Jihad leader had earlier told Xinhua that the visit of the two delegations to Cairo aimed at discussing the recent developments in the Gaza Strip and the calm understandings with Israel.

The group's official accused Israel of not being committed to the understandings, mainly lifting an Israeli blockade that had been imposed on the Gaza Strip since 2007.

Egypt and the United Nations have been mediating for several months a calm understanding between the Palestinian factions in the Gaza Strip and Israel trying to ease the hard living situation in the coastal enclave.
