GAZA - A $15 million Qatari cash infusion was paid out to impoverished Palestinian civil servants in the Gaza Strip on Friday, offering the enclave’s dominant Hamas Islamists a potential domestic reprieve though Israel said the money would not go to them.

Hamas’s political rival based in the West Bank, Palestinian President Mahmoud Abbas, has slashed Gaza budgets, beggaring tens of thousands of government employees. That has helped stoke a half-year of bloody protests and occasional shelling exchanges across the border of Gaza, which Israel keeps under blockade.

Palestinian sources said the Qatari payout, received on Thursday, was the first of a total of $90 million that would come into Gaza over the next six months with Israeli approval. Israel had previously agreed to the gas-rich Gulf Arab state donating materials for civilian construction projects or fuel, worried that more fungible cash donations could reach Hamas guerrillas, with which it has fought three wars in a decade.

“One day, I have no money to get food or medicine for my children - and now I will buy them food, medicine and clothes,” said Wael Abu Assi, a traffic policeman, outside a Gaza City post office where people queued to draw their salaries.

Branded a terrorist group in the West, Hamas has been under years of embargo by Israel and neighbouring Egypt. Hamas leaders said in the past they had received funds from other countries including Iran. Observers for Qatar were present at all 12 post offices across Gaza to monitor the salary disbursements. Employees had to present their identity card and be finger-printed.

 “Long live Qatar!” shouted youths who greeting Doha’s point-man for Gaza relief efforts, Mohammed Al-Emadi, at a site near the border with Israel which has seen frequent demonstrations. “Long live Gaza!” he replied. But as the diplomat’s convoy departed, some youths threw stones that smashed a window on his bodyguards’ car - suggesting not all Palestinian protesters were pleased with Qatar’s intervention. Al-Emadi’s car was unscathed.

Qatar’s official news agency said the donated money would benefit 27,000 civil servants. “The salaries for the others will be paid from local revenue,” it said. Hamas has hired over 40,000 people in Gaza since 2007 but many appeared to have been excluded from the list of payees. “They told me they don’t have money for me,” one employee told Reuters on condition tat he would not be named. “Maybe Israel vetoed my name?”

Officials from Hamas, Qatar and Israel have been largely silent about the details of the Gaza payouts arrangement. But a member of right-wing Israeli Prime Minister Benjamin Netanyahu’s security cabinet played down their significance.

“This is not money that is going to Hamas activities. It is money that is going to the salaries of civil servants, in an orderly, organised manner,” Environment Minister Zeev Elkin told Tel Aviv radio station 102 FM.

Elkin accused Abbas, whose peace talks with Netanyahu stalled in 2014 and who is boycotting the United States because of its pro-Israel policies, of cutting salaries to “inflame Gaza, because he has not been successful on other fronts”. “The Qataris came along and said: ‘We are willing to pay this instead of Abu Mazen (Abbas), in order to calm Gaza down’. What does it matter who pays it?” Elkin said.

Wasel Abu Youssef, a member of the executive committee of the Abbas-led Palestine Liberation Organization, criticised the move. “Arrangements through Qatar and elsewhere prolong the crisis of Palestinian division,” Abu Youssef told Reuters.

Doha’s donation, as well as U.N.-Egyptian truce mediation and winter rains, have tamped down the violence at the border, where Gaza medics say Israeli army fire has killed more than 220 Palestinians since the protests began on March 30.

Israel, which says its lethal force prevents armed infiltration, has lost a soldier to a Gaza sniper and tracts of forest and farmland to incendiary material flown over the frontier on kites or helium balloons.

“This is one of the fruits of the ‘March of Return’,” Abraham Baker, a police officer who received a full salary, said, using the Palestinian term for the protests, which demand rights to lands lost to Israel’s in the 1948 war of its founding.
