Egypt has banned two prominent political figures from leaving the country because they are under investigation for allegedly inciting deadly violence last month, state news agency MENA said on Tuesday.
The ban by the state prosecutor applies to Ayman Nur, founder of the Al-Ghad party, and Mamduh Hamza, a prominent figure among the youth who spearheaded the popular revolt that led to the ouster of president Hosni Mubarak in February.
MENA did not say what either of the two men were thought to have done.
On December 16, clashes broke out between security forces and protesters holding a sit-in outside the cabinet office to protest the appointment of Kamal al-Ganzuri, a former Mubarak stalwart, as interim prime minister.
Seventeen protesters were killed.
The clashes were the bloodiest since five days of protests in November killed at least 42 people just ahead of the first general election since Mubarak stepped down.
Nur unsuccessfully stood against Mubarak in the 2005 presidential election.
He was later sentenced to five years in jail for fraud and falsification of documents, charges he denied, and was released in 2009 for health reasons.
