Israel and the Palestinian Authority are concerned that al-Qaeda terrorists could infiltrate into Gaza from Egypt, now that the border has collapsed. Officials on both sides say Al Qaeda could link up with Palestinians from Hamas and the Islamic Jihad. “We are even more worried than Israel about al-Qaeda coming here because al-Qaeda will harm us more than Israel," said Rafiq Husseini, the top aide to Palestinian leader Mahmoud Abbas. Israel is worried about mega-terror on its soil, and the Palestinian Authority fears that it could be toppled and replaced with an Iranian-style regime.
