Egyptian protesters have thrown tomatoes and shoes at US Secretary of State Hillary Clinton's motorcade Sunday and shouted, "Monica, Monica, Monica" as she left the newly reopened US Consulate in Alexandria, CNN reported.

Clinton said she was in the city to answer critics who believe Washington has taken sides in Egyptian politics. There were already vocal protesters at the start of her visit to the consulate, forcing the ceremony to be moved inside.

"I want to be clear that the United States is not in the business, in Egypt, of choosing winners and losers, even if we could, which, of course, we cannot," Clinton said at the ceremony to reopen the consulate, which was closed in 1993 because of budget constraints.

"I have come to Alexandria to reaffirm the strong support of the United States for the Egyptian people and for their democratic future."

The protesters reportedly threw the tomatoes, shoes and a water bottle as the staff walked to their vans after the ceremony and riot police had to hold back the crowd. A tomato hit an Egyptian official in the face.

Clinton's van was around the corner from the protesters, and a senior State Department official said her car was not hit.

The chants of "Monica" refer to Monica Lewinsky, the White House intern who had an affair with Clinton's husband, former President Bill Clinton.

Earlier Sunday, Clinton held a closed-door meeting with the head of Egypt's military leadership, Field Marshal Mohamed Hussein Tantawi, whose military council is in a political tug of war with new President Mohamed Morsy.
