An Egyptian security source denied in comments published Tuesday Israel's claim that Al-Qaeda network established a base in the Sinai Peninsula. Al-Gumhuriyah daily quoted the source as saying "that there is absolutely no Al-Qaeda base in Sinai," adding that the security forces are still operating in Sinai to control "all elements still at large within Al-Halal mountain after taking part in the recent Sinai attacks."On Sunday, Israel's Intelligence Chief Gen. Ze'evi-Farkash said Al-Qaeda had built at least one base in Sinai, from where activists are sent to Gaza Strip and from there to Israel.
