Mubarak supporters clash with protesters in Cairo; men charge into square on horses, camels + PIC

(AhlulBayt News Agency) - At one point, men riding horses and camels charged into the square and began lashing people with whips, before some were pulled off their mounts and beaten by angry mobs, according to local reports.

The rioting was the first violent clash between anti-government demonstrators and Mubarak supporters, who gathered in the square in larger numbers than seen before, according to news reports.

Dozens of bloody protesters were seen being led away from the square after being hit with rocks, bottles or clubs, and many were being treated for wounds at makeshift clinics nearby, according to CNN.

Soldiers – who were initially standing by as the rioting spilled into the streets around the square -- eventually stepped in and began separating the demonstrators with military vehicles and tossing tear gas

The sound of gunfire was also heard, CNN reported.

The rioting erupted one day after Mubarak, the autocratic ruler of Egypt for three decades, buckled to pressure from his own military and outside governments and vowed to step down.

But his promise to remain in office until a presidential election in September angered his opponents, who demanded he leave office immediately.

The crowds in Tahrir Square grew after the speech, with pro-Mubarak demonstrators arriving in large numbers for the first time in a week.

Small skirmishes between the two groups began in both Cairo and Alexandria after midnight local time, according to reports.

Earlier in the day, the military urged the demonstrators to return to their homes to allow life to return to normal on the streets of Cairo.

"Your message was received and we know your demands," the spokesman said in a television broadcast. "We are with you and for you."

But the plea was largely ignored.

The square was already packed with protesters shortly after dawn on Wednesday, as many people, including families with small children, slept in tents overnight.

President Obama said he spent 30 minutes on the phone with Mubarak, "an important regional ally" before the Egyptian president made his announcement on state TV.

During the phone call, Obama insisted on a rapid transition, the New York Times reported.

Publically, Obama did not call on Mubarak to step down, but said an orderly transition in Egypt "must be meaningful, must be peaceful and must begin now."

In response to the growing tension, governments continued to call for the safe removal of their citizens from the region.

Australian Prime Minister Julia Gillard said emergency flights would begin to pull Australians out of Cairo on Wednesday.

Britain was organizing extra flights to bring British nationals back to the U.K., according to CNN, and Greece sent military aircraft to evacuate more than 200 Greeks from Egypt, the official Athens News Agency said.
