The terror group has been unable to pay its fighters or repair its network of tunnels and hideouts beneath the Strip. Cash shortages have reportedly left Hamas unable to pay salaries for police and ministry employees. Money reserves amassed before, or during the early stages of, the war have run short, while Israeli strikes have devastated the leadership and fractured its grip on the besieged territory. Hamas for years received large sums from Iran, Qatar and others, and was also able to tax cross-border commerce. Israel has long alleged that Hamas also made money by seizing and selling international aid entering Gaza, though this has been denied by the United Nations and aid agencies.
