"They just want to sow fear and confusion among the people," Haniyeh said.
Israeli forces have launched a series of airstrikes, armored incursions and artillery bombardments in Gaza since June 25, when militants staged a cross-border attack that killed two Israeli soldiers and took a third captive. At least 145 Palestinians have been killed and hundreds wounded in the fighting. In addition to seeking the return of Cpl. Gilad Shalit, the Israeli army says it wants to end rocket attacks on southern Israeli towns.
Though Palestinians report that dozens of warnings have been received in the last two weeks, only a handful of buildings have been hit.
"They think they're above the law. They have no red lines," said Ghazi Hamad, a spokesman for the Hamas-led Palestinian Authority. "They listen to nobody, except maybe the Americans."
Israeli army officials are tight-lipped about the practice and won't discuss individual cases. The official daily updates of the army's attacks on suspected weapons factories and warehouses in the Gaza Strip invariably mention steps taken to warn residents and limit civilian casualties.
"It is a method that's being used to prevent the harming of innocent civilians," said one army spokeswoman, who spoke on condition of anonymity.
Calls have also targeted official buildings such as the main Gaza City courthouse and the ambulance dispatch center at Khan Yunis hospital, said Iyad Nasr, spokesman for the International Committee of the Red Cross. Neither site has been hit.
"It's still collective punishment," Nasr said. "Dozens of families have been informed and have evacuated their homes."
The first known case of a pre-strike warning call came July 23, targeting the Gaza City home of Mohammed Sheik Dib. In that case, neighbors generally acknowledge that Dib was a ranking member of the Islamic Jihad militant group and that rockets probably were being stored in the house. Islamic Jihad gunmen surrounded the house immediately after the attack, and barred all access.
Others such as Mamluke say they are victims of mistaken identity.
"They think I'm some sort of leader in Hamas. But I don't even pray," he said.
Several days after the July 24 bombing, Mamluke, 44, walked through the remnants of his home. The ceiling pancaked onto the lower floors, and the entire lot was left knee-deep in rubble.
