The Egyptian armed forces announced on Sunday that 89 "Takfiris" were killed in anti-terrorism operations in the Sinai Peninsula.
According to an armed forces statement, most of the fighting took place in the northern Sinai, where militants loyal to ISIS operate, "during the last period".
It said that eight Egyptian army soldiers have been killed in the operations.
Eighty-nine "very dangerous Takfiris" were also killed during the fighting in northern Sinai, the statement said, using a term it normally employs to refer to suspected militants.
The army confiscated different types of arms and ammunition during the operations and destroyed hundreds of explosive devices and some explosive belts, Reuters reported. It also destroyed 13 tunnel entrances used to infiltrate the North Sinai region, which has borders with the Gaza Strip and Israel.
Air forces, in coordination with border guards, also attacked and destroyed 200 vehicles, some of them loaded with arms and ammunition, while trying to penetrate the western and southern borders of the country, the statement said.
Libya borders Egypt from the west and Sudan borders it from the south.
