Some 300 unemployed Palestinian laborers surrounded the parliament building in Gaza City on Tuesday, demanding welfare payments and scuffling with police. The Hamas-led government is broke because of an international aid freeze that began in March. The government has been unable to pay its 165,000 employees and distribute welfare payments. On Monday, Palestinian Prime Minister Ismail Haniyeh promised one-time unemployment payments of $100 (â‚¬78) to 50,000 workers. The public servants' union, meanwhile, threatened to launch an open-ended strike next week to protest the non-payment of salaries. The strike is expected to paralyze Palestinian schools and disrupt service in government hospitals.
