A top Hamas police commander met in mid-March with the heads of a Gaza clan who’d been commandeering aid meant for hungry Palestinians. He told them to stop taking the shipments or they’d be killed. A week later, that commander was killed — by Israeli troops.

The Israelis weren’t acting at the clan’s request. Rather, all three — Hamas, clans and the Israeli military — are engaged in a bloody battle for control of north Gaza and aid distribution, making an already troubled process more dangerous and unreliable. Famine is a threat, and people are beginning to die of hunger, according to the Hamas-run health ministry.

The dead commander, Fayeq al-Mabhouh, had organized a safe route so that those who’d been desperately making bread from animal feed got wheat flour, according to a senior Hamas official and several others on the ground, speaking on the condition of anonymity. Israeli troops killed several others working with Mabhouh, Gazans say, and the safe route died with them.
