Tunisian police detained a Ukrainian topless activist in the capital Tunis before expelling her from the North African country on Tuesday, a leader of the women's protest movement Femen said.

"Some men entered her hotel room, ordered her to take her belongings and drove to the police... She was deported and is now on a plane to Kiev. Her passport has been given to the pilot," Femen's leader in Paris, Inna Shevchenko, told Agence France Presse on the phone.

Turkish premier Recep Tayyip Erdogan left Morocco for Algeria on Tuesday, the second leg of a North African tour, as the worst political crisis of his 10 years in power showed no sign of abating.

After arriving on Monday at the head of a senior ministerial delegation and accompanied by a large number of businessmen, he and Moroccan counterpart Abdelilah Benkirane signed a joint political declaration on developing strategic ties, official Moroccan media said.

Three Tunisian soldiers hunting al-Qaida-linked jihadists in the rugged border region near Algeria have been wounded in a mine explosion on Mount Chaambi, the defense ministry said.

"The blast happened at 6:15 pm (1715 GMT on Saturday) under a military vehicle, wounding three soldiers," ministry spokesman Colonel Mokhtar Ben Nasr told Agence France Presse.

Tunisia's interior ministry banned a rally in Tunis on Saturday by a controversial militia linked to the ruling Islamist Ennahda party but dozens flaunted the order and gathered anyway.

A branch of the League for the Protection of the Revolution in the capital's suburb of Kram had called for the rally to demand that a controversial bill on the "immunization" of the revolution be adopted quickly.

Three European women with radical activist group Femen, who were arrested after baring their breasts in Tunis, will be tried next week for public indecency and could be jailed, their lawyer said Friday.

"They will appear in court in Tunis on June 5... The trial will be an open hearing," Souheib Bahri told Agence France Presse, information confirmed by French consular officials in Tunis.

Tunisian prosecutors are to appeal the "lenient" suspended jail sentences handed down against 20 people for their roles in an attack on the U.S. embassy last year, the justice minister said on Friday.

Washington had said it was "deeply troubled" by the sentences.

A Tunisian judge on Thursday announced fresh charges against a young Tunisian woman with the topless protest group Femen, as three Europeans began a second night in custody after baring their breasts.

Amina Sboui, better known by her pseudonym Tyler, was remanded in custody and would be charged with indecency and desecrating a cemetery, crimes punishable by up to two years in jail, the presiding judge told Agence France Presse.

The U.S. embassy in Tunis said Wednesday it was "deeply troubled" by the leniency of two-year suspended sentences handed out to 20 people implicated in an attack on the mission.

"We are deeply troubled by reports of suspended sentences. The verdicts do not correspond appropriately to the extent and severity of the damage and violence that took place on September 14, 2012," the embassy said in a statement.

Three young European women with topless protest group Femen were arrested Wednesday after baring their breasts in Tunis, a first in the Arab world that sparked scuffles outside the Tunisian capital's main courthouse.

Standing on a wall in front of the railings outside the courthouse, the women, two French and the other German, shouted: "Free Amina," in support of a young Tunisian woman detained while protesting against hardline Islamists and awaiting trial on Thursday.

Twenty people implicated in a deadly attack on the U.S. embassy in the Tunisian capital last year, some of whom could face the death penalty, insisted they were innocent as their trial opened on Tuesday.
