Some Western countries, such as Britain, the United States and France, have advised their citizens to return home and warned against travelling to Egypt.

However, some Austrian tourists said they had no fear and felt safe during their stay in Egypt.

They made tours to the city of Sharm el-Sheikh on the Red Sea and Cairo, the capital of Egypt, and arrived at Vienna International Airport safely on Saturday.

According to the Austrian Press Agency (APA), during their stay in Egypt, most of the Austrian tourists acquired insight into the unrest primarily through television.

Only a few got a little first-hand information about the unrest in the capital. "As we drove towards the airport, we saw two large houses burned. Below were tanks. And otherwise it was really quiet. There was less traffic," said a Vienna native.

Also at the airport in Cairo, the situation was relaxed, the Austrian tourists said. There was no increasing number of security persons or police, said an Austrian, who tansit in airport of Cairo on its way from South Africa to Vienna.

Saudi King announced his support to Mubarak amid the protests. Arab League Secretary-General Amr Moussa, a former Egyptian foreign minister, said in an interview with Al Jazeera that the Egyptian regime must respect the people's requests.
