The attacks wielding swords in Egypt are portents of the coming of Hazrat Mahdi (as) as foretold by our Prophet (saas)

Ibn Abi Shayba narrated from Abi Jald that he said: Corruption will be seen, and other corruptions will follow it and THE FIRST WILL PROVOKE THE PASAGE OF THE LAST INTO FIGHTING WITH SWORDS, and after that will come a corruption in which all that is unlawful will be regarded as lawful. And then the caliphate will come to Hazrat Mahdi (as), the most auspicious of men, as he sits at home. (Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, 4.1)

In the incidents in Egypt, Mubarak supporters began attacking the protesters, using SWORDS, KNIVES AND CLEAVERS. The way these incidents happened just as foretold by our Prophet (saas) is one of the miracles bestowed on our Prophet (saas) by Allah.
