Activists across Egypt held strikes and demonstrations Saturday to mark the first anniversary of President Hosni Mubarak's ouster, but the turnout was modest.

The day of civil disobedience was called to demand that the ruling military council hand over power to civilian authority. But the strikes seemed to cause little disruption and only a few protesters gathered in Cairo's Tahrir Square.

Also Saturday, Egyptian police arrested an Australian journalist, an American student and their Egyptian interpreter in the city of Mahalla on accusations of trying to pay people to encourage them to participate in the protests.

The latest move against foreigners came the same day as the top U.S. general met with Egypt's military rulers in Cairo amid tensions over an investigation into alleged illegal foreign funding of non-governmental organizations.

Egypt has brought criminal charges against 43 local and foreign activists, including 19 Americans. The foreign groups are accused of interfering in Egyptian affairs. The issue has prompted calls in Washington to cut $1.3 billion in U.S. military aid to Egypt.

In an unrelated development Saturday, Egyptian officials said three South Korean tourists and their Egyptian tour guide, kidnapped a day earlier in the Sinai peninsula by a group of armed tribesmen, were freed unharmed.

Egypt's military rulers have promised to stage a presidential election by June to complete a democratic transition to civilian rule. The ruling military also held a phased parliamentary election that led to last month's formation of a new assembly dominated by Islamist parties.
