CAIRO, January 13 (RIA Novosti) - About ten people were injured in the Egyptian capital Cairo when a group of unidentified men attacked an opposition tent camp, the country’s interior ministry said on Sunday.

According to the ministry’s emergency report, a group of armed men hurled Moltov cocktails at a tent camp outside the presidential palace in the Al-Ittihadia district. Several tents caught fire.

Sporadic fights broke out when the sit-in participants clashed with the attackers.

Palace guards used tear gas in an attempt to disperse the crowd. Over ten people were wounded, some of them were rushed to hospital with serious injuries.

The interior ministry said an officer and six police were injured the fighting.

The violence was eventually quelled, but the situation remains tense in downtown Cairo.

The area outside the presidential palace became a scene of deadly clashes a month ago, following a political crisis triggered by President Mohammed Morsi's November 22 constitutional declaration.
