Gunmen have shot dead an Egyptian soldier in Sinai as army helicopters carried out air strikes on suspected militant hideouts, medics and witnesses say.
The 22-year-old conscript died of a chest wound after the attack in the northern town of Sheikh Zuwayid, medics said on Saturday.
Apache helicopters launched another day of raids in the weeks-long campaign to crush Islamist insurgents in the peninsula, targeting suspected hideouts around Sheikh Zuwayid, witnesses said.
Meanwhile, a video purporting to show militants attacking Egyptian troops was posted on an Islamist jihadi internet forum on Saturday.
It showed a roadside bomb targeting what appeared to be an armoured personnel carrier, and included threats of further attacks.
