Egypt's Cabinet on Wednesday declared the Muslim Brotherhood a "terrorist group and organization," Higher Education Minister Hossam Eissa said in a statement.

The statement broadcast by state-run news agency Mena was issued in response to a suicide attack early Tuesday on a police station in the Nile Delta city of Mansoura that the military-backed interim government says killed 16.

The government attributed the attack to the Muslim Brotherhood even though that group denies any involvement and on Wednesday the Al Qaeda-inspired Ansar Beit Al-Maqdis group claimed responsibility.

The declaration outlaws all of the Muslim Brotherhood's activities and any funding of the organization.

The Brotherhood and allied groups have held demonstrations at universities across Egypt since Islamist President Mohamed Morsi was deposed by the armed forces in a July 3 coup, which followed days of massive anti-government protests.

Morsi is on trial for inciting the murder of his opponents and also faces other charges including treason that are punishable by execution.

While in office from June 2012 to July 2013, Morsi and the Brotherhood were accused by critics of doing little to address poverty and Egypt's struggling economy, of failing to advance the goals of the 2011 revolution that forced out strongman Hosni Mubarak and of seeking to monopolize power. EFE
