Twenty-eight people were detained in the Bulgarian capital Sofia on Sunday during a 10th consecutive evening of anti-government protests, in order to prevent a potential escalation, police said Monday.

Another 200 people identified as potential troublemakers were also stopped from joining the main demonstration in downtown Sofia of several thousand people, police added.

Chairman of the Knesset Foreign Affairs and Defense Committee Avigdor Lieberman slammed the European Union on Monday for failing to label Hizbullah as a terrorist organization.

He labeled the move as “ultimate hypocrisy."

Bulgaria denied Thursday backtracking over whether Hizbullah was behind a bomb attack last July on its soil that killed five Israelis, saying earlier comments were misinterpreted.

"Bulgaria has not revised its stance on the terrorist act," Foreign Minister Kristian Vigenin was cited in a statement as telling Ireland's ambassador to Sofia John Rowan in talks.

Bulgaria's new foreign minister said Wednesday that evidence Hizbullah was behind a bomb attack last July on its soil that killed five Israelis was "circumstantial" and "not categorical" at this stage.

The minister, Kristian Vigenin, said that as a result, Sofia would not back the European Union labeling the Lebanese organization's military wing a "terrorist" entity without proof from other cases.

Bulgaria's parliament on Wednesday confirmed economist Plamen Oresharski as new prime minister to head a Socialist-backed anti-crisis cabinet of technocrats, ending a post-election stalemate in the EU's poorest country.

Oresharski won support from 120 out of the 217 lawmakers present in the divided 240-seat parliament, with 97 opposed.

Bulgarian authorities said Saturday they seized 350,000 illegal ballot papers a day before elections, sparking furious opposition accusations of fraud against the former ruling party of ex-premier Boyko Borisov.

Socialist party leader Sergey Stanishev said the discovery was "preparation for total falsification of the elections."

Bulgarian investigators on Friday re-enacted a July 2012 bomb attack blamed by Sofia on Hizbullah that killed five Israelis, blowing up two old buses and 11 silicon mannequins in a controlled explosion.

The aim was "to provide information and important evidence on the type and quantity of explosive used" in the attack at Burgas airport on the Black Sea, chief investigator Boyko Naydenov said.

The kidnapped 10-year-old daughter of one of Bulgaria's alleged cocaine-trafficking lords, Evelin "Brendo" Banev has been released after 47 days in captivity, police said Monday.

Lara Baneva was left at a parking lot in the capital around 10:00 pm (1900 GMT) Sunday and walked to a nearby police station, the interior ministry said.

The Bulgarian Charge d'Affaires in Lebanon, Plamen Tzolov, said his government was still waiting for the cooperation of the Lebanese authorities on the investigation into the bus bombing on Israeli tourists last year.

In remarks to As Safir daily published Thursday, Tzolov said: “The Bulgarian government is still waiting for the response of the Lebanese government and mainly the justice ministry on a request made by Bulgaria to cooperate on this security file.”

Bulgaria's Pomak Muslim minority marked on Saturday the 40th anniversary of the crackdown on a revolt against the then communist regime's assimilation drive to forcefully change their names to non-Muslim ones.

Members of the 200,000-strong minority -- whose Christian ancestors were converted to Islam while Bulgaria was ruled by the Ottomans between the 14th and 19th centuries -- gathered at a square in the southwestern village of Kornitsa in memory of the five people killed there on the night of March 28, 1973.
