JERUSALEM, Israel - Egyptian President Hosni Mubarak named a vice president Saturday for the first time since coming to power nearly 30 years ago.
The move was seen as a step toward setting up a successor in the midst of the biggest challenge ever to his rule from tens of thousands of anti-government protesters.
Mubarak named his intelligence chief and close confidant Omar Suleiman, state television reported.

An estimated 50,000 resumed clashes with police in Cairo's Tahrir Square on Saturday, within eye view of army personnel deployed nearby.
Since Tuesday, rioting and widespread burning and looting has engulfed the country, with some protesters calling it a revolution, not just demonstrations or protests.
On Friday, an al-Jazeera correspondent in Alexandria reported seeing 23 bodies at the morgue following Friday's demonstrations. In Suez, at least 27 protesters were killed when police opened fired to disperse them, according to the report. At least 22 people have died in Cairo.
Meanwhile, Mubarak ordered cell phone service restored but not Internet service. Protesters - continuing to call on Mubarak to resign - have used social networking to coordinate their plans.
