Muslim Brotherhood

According to the Galil Report:

In response to the heated rhetoric and to specific warnings regarding other terror groups, particularly al-Qaida-affiliated cells in Sinai, Egypt has raised the level of alertness in the country and has placed security agencies on heightened alert levels.

The Muslim Brotherhood, a fundamentalist Islamic group and its' Palestinian branch, Hamas, have ambitions to construct a pan-Arab theocracy all the way through the entire Middle East.

Hosni Mubarak sees the Muslim Brotherhood as a major threat to the current Egyptian government. In the last election cycle, the "Brotherhood", crushing all other opposition parties, won a history-making 20 percent of the Parliament, despite widely reported tales of monumental election tampering by Mubarak's National Democratic Party. It was also reported that just before the elections, he had more than 1,500 "Brotherhood" activists arrested.

Further, the Galil Report states,

A number of Brotherhood leaders in Egypt have told reporters their group is strengthened by the Hamas ascension to power in the Palestinian territories and that they plan a similar power grab in Egypt.
