Israeli aircraft struck Hamas security installations in Gaza on Friday, killing at least one Palestinian, in further retaliation for attacks along the Egyptian border in which eight Israelis died.
Gaza residents said three compounds controlled by the Hamas Islamist group that rules the enclave were hit in the overnight raids. Medical officials said a 13-year-old boy in a nearby building was killed and 17 people were wounded. There was no immediate word on casualties among militants.
The series of assaults by gunmen on a desert road north of Israel's Red Sea resort of Eilat on Thursday drew Israeli accusations that Egypt's new rulers were losing their grip on the porous frontier.
Israel said the attackers infiltrated from the Hamas-run Gaza Strip via Egypt's Sinai desert, despite stepped up efforts by Egyptian security forces in recent days to rein in Palestinian and Islamist radicals.
