As for the leaders of the Palestinians in the West Bank and Gaza Strip? They are otherwise occupied. Mahmoud Abbas's Palestinian Authority and Hamas are too busy lunging at each other's throats and trying to take down Israel to pay much attention to their people's suffering in Syria.

UNRWA said that of the estimated 438,000 Palestine refugees remaining inside Syria, more than 95% (418,000) are in critical need of sustained humanitarian assistance.

Dropping barrels of dynamite on houses and hospitals in a Palestinian refugee camp is apparently of no interest to those who pretend to champion Palestinians around the world. Nor does the issue seem to move the UN Security Council.

While all eyes are set on the weekly demonstrations organized by Hamas and other Palestinian factions along the border between the Gaza Strip and Israel, as part of the so-called March of Return, a Palestinian refugee camp near Damascus is facing a wide-scale military offensive and ethnic cleansing by the Syrian army and its allies.

The war crimes committed against the Palestinians in Yarmouk camp have so far failed to prompt an ounce of outrage, much less the sort of outcry emerging from the international community over the events of the past four weeks along the border between the Gaza Strip and Israel.

The international community seems to differentiate between a Palestinian shot by an Israeli soldier and a Palestinian shot by a Syrian soldier.

In the first case, Hamas and several Palestinian groups have been encouraging Palestinians to march towards the border with Israel, with some even trying to destroy the security fence and hurling stones and petrol bombs at Israeli troops. The organizers of the Gaza demonstrations say their real goal is to "achieve the right of return and return to all of Palestine."

Dozens of local and foreign journalists have shown great interest in the "March of Return." Reporters from different parts of the world have been converging on the Gaza Strip and the border with Israel to report about the weekly demonstrations and clashes between Palestinians and Israeli soldiers.

How many journalists, though, have traveled to Syria to cover the plight of the Palestinians in that country? A small handful, perhaps? Why? Because the Palestinians who are being maimed and murdered in Syria are the victims of an Arab army -- nothing to do with Israel.

Yarmouk camp was once home to some 160,000 Palestinians. Since the beginning of the civil war in Syria, however, the number of residents left in the camp is estimated at a few hundred.

On April 19, the Syrian army and its allies, including the Russians, launched a massive offensive against opposition groups and Islamic State terrorists based in Yarmouk.

Since then, 5,000 of the 6,000 residents left in Yarmouk have fled the camp, according to the United Nations and human rights organizations. Most of the camp's houses have been destroyed in the past few years as a result of the fighting between the Syrian army and opposition groups that found shelter inside Yarmouk.

Yarmouk has been under the full siege of the Syrian army since 2013, a situation that has caused a humanitarian crisis for the residents. According to some reports, the situation has gotten so bad that residents living there have been forced to eat dogs and cats to survive.

In the past week, at least 15 Palestinians have been killed in airstrikes and artillery shelling on Yarmouk.

According to the London-based Action Group for Palestinians of Syria, 3,722 Palestinians (including 465 women) have been killed since the beginning of the civil war in Syria in 2011. Another 1,675 are said to have been detained by the Syrian authorities, and another 309 are listed as missing.

More than 200 of the Palestinian victims died because of the lack of food and medical care, most of them in Yarmouk. Since the beginning of the civil war, some 120,000 Palestinians have fled Syria to Europe. An additional 31,000 fled to Lebanon, 17,000 to Jordan, 6,000 to Egypt, 8,000 to Turkey and 1,000 to the Gaza Strip.

On April 24, Syrian and Russian warplanes carried out more than 85 airstrikes on Yarmouk camp and dropped 24 barrels of explosives; 24 rocket and dozens of missiles were fired at the camp.

A day earlier, Syrian and Russian warplanes launched 220 airstrikes on Yarmouk camp. The warplanes dropped 55 barrels of dynamite on the camp, which was also targeted with 108 rockets and missiles.

According to the United Nations Relief and Works Agency for Palestine Refugees (UNRWA), the conflict in Syria "continues to disrupt the lives of civilians, resulting in death and injuries, internal displacement, extensive damage to civilian infrastructure and persistent humanitarian needs. Affected communities suffer indiscriminate violence, restrictions on their freedom of movement and continued violations of international humanitarian and human rights law. Palestinians are among those worst affected by the conflict."

UNRWA said that of the estimated 438,000 Palestine refugees remaining inside Syria, more than 95% (418,000) are in critical need of sustained humanitarian assistance. Almost 254,000 are internally displaced, and an estimated 56,600 are trapped in hard-to-reach or wholly inaccessible locations.

The silence of the international community to the war crimes being committed against defenseless Palestinians in a refugee camp in Syria is an insult.

Dropping barrels of dynamite on houses and hospitals in a Palestinian refugee camp is apparently of no interest to those who pretend to champion Palestinians around the world. Nor does the issue seem to move the UN Security Council.

But the border between the Gaza Strip and Israel: for the world, that is where the real story is unfolding. Certainly not in Syria, where Palestinians face ethnic cleansing on a daily basis.

As for the leaders of the Palestinians in the West Bank and Gaza Strip? They are otherwise occupied. Mahmoud Abbas's Palestinian Authority and Hamas are too busy lunging at each other's throats and trying to take down Israel to pay much attention to their people's suffering in Syria.

For the past four weeks, the two rival Palestinian parties have been castigating Israel for its actions along its border with the Gaza Strip. They have also been calling on the international community to hold Israel accountable for its "crimes" against Palestinians.

But when it comes to atrocities being committed against their people in an Arab country, words apparently fail Palestinian leaders. Assad and his army can slaughter Palestinians and launch airstrikes on a Palestinian camp without a whimper of protest from Hamas or the Palestinian Authority. In fact, all one hears is the silence of the dead.
