CAIRO (Reuters) - Egypt said on Thursday its air force had hit 10 four-wheel-drive vehicles carrying arms, ammunition and contraband at Egypt’s western borders with Libya.

Egyptian security forces have been battling an insurgency by Islamic State that was until recently concentrated in the Sinai Peninsula but has extended to other parts of the country.

“A number of criminals gathered and prepared to sneak into the Egyptian border, using a number of four-wheel-drive vehicles,” the Egyptian military said in a statement that gave no details of casualties.
