Israelis target ISIS fighters in Egypt as part of covert counterterrorism pact

Unmarked Israeli warplanes and helicopters have carried out dozens of covert attacks against the Islamic State and other terrorist groups inside the Egyptian Sinai in recent years, said two former senior U.S. officials.

The airstrikes by Israeli planes are conducted with the support of President Abdel Fatah al-Sissi, who has led an often brutal campaign inside Egypt to wipe out the Islamist militant groups but has struggled to defeat them.
