Cairo's Tahrir Square was mostly calm after a night of clashes between police forces and protesters who were commemorating November 2011 clashes with security that killed more than 40 demonstrators, although protesters blocked portions of Qasr al-Aini street near the entrance to the square.

Violence erupted at Mohamed Mahmoud street, near the Interior Ministry, last year after police forces had forcibly cleared the square of protesters against the Supreme Council of the Armed Forces that had ruled the country during its transitional period.

Nearly 36 protesters were injured in clashes during the demonstrations marking the events late Monday, the Health Ministry said in an earlier statement.

Dozens of men blocked Qasr al-Aini using wooden pallets at Sheikh Rihan Street which leads to the Interior Ministry, eyewitnesses reported. The charred remains of fires lit the night before remained on the street.

Activities returned to normal on Tuesday at the Mugamma, where employees began work according to their usual schedule. Workers at the nearby Shura Council, other vital institutions and shops also resumed regular schedules.
