A group of Egyptian hackers on Sunday penetrated an Israeli radio website, posting an image of the Egyptian flag on the page.
Under the flag, the hackers wrote an angry message saying any attack by Israel on Egypt's borders will not be forgiven.
The cyber attack came minutes after a young Egyptian protester climbed up to the roof of the building housing the Israeli embassy in Giza and replaced the Israeli flag with an Egyptian one.
Hundreds of protesters have been demonstrating since Friday in front of the embassy, voicing rage over an Israeli border raid that killed six Egyptian officers on Thursday.
