Tunis , Tunisia ( CNN ) -- Tunisian opposition leaders joined the current ruling party Monday in a new government to replace the country 's ousted president , while U.N. Secretary-General Ban Ki-moon called for a return to stability `` as soon as possible . '' The government will be led by current Prime Minister Mohamed Ghannouchi , who took charge of the North African country when longtime President Zine El Abidine Ben Ali fled last week . Ghannouchi 's 19-member Cabinet will include three opposition leaders and 10 independents , he announced Monday . The new government will be tasked with leading Tunisia toward new elections , he said . Street clashes continued in Tunis on Monday , three days after Ben Ali 's departure , with police firing tear gas into crowds of demonstrators in Tunis . Ban called on the new government to restore stability and the rule of law `` as soon as possible . '' Ben Ali fled to Saudi Arabia on Friday after ruling the country for 23 years . His ouster followed weeks of protest over what Tunisians said were poor living conditions , high unemployment , government corruption and repression . Fouad Mebazaa , a former parliament speaker , was named acting president Saturday . He promised to restore stability and respect the constitution of the North African country . Speaking in Abu Dhabi , Ban told reporters the new government should protect human rights and guarantee freedom of speech and association . But he said he remained `` extremely concerned '' about the ongoing clashes in the streets . `` This is a moment for the Tunisian people to strengthen the country 's longstanding culture of political moderation and its attachment to peace , '' he said . `` I call on the government and all stakeholders to ensure a prompt restoration of the rule of law , and to respect and accommodate the aspirations of the people . Tunisia must regain its stability as soon as possible , to pursue the path of development and prosperity . '' The new government includes opposition leaders Mustafa Ben Jaafar , who will serve as health minister ; Ahmad Ibrahim , education minister ; and Ahmad Najib Al Shabi , minister of local development . Among the holdovers is Ahmad Friaa , the interior minister . Friaa , speaking later on state TV , said 78 people have died in the clashes across several weeks and 94 have been injured , among them many police officers . He urged people to stop riots and to work with police . He vowed that those who should be held responsible for mistakes of the past will be punished . And Friaa ended his speech saying , `` Yes for democracy , yes freedom , no for chaos . '' Friaa also said the cost of the turmoil of recent weeks is 3 billion Tunisian dinars ( about 1.6 billion euros , about $ 2 billion U.S. ) . The announcements came a day after the country 's army clashed with armed gangs and remnants of Ben Ali 's personal guard . Police have arrested looters and as many as two dozen of the ousted president 's relatives since Friday . Public protests continued Monday , as about two thousand people packed into a major road in Tunis . As the demonstrators tried to work their way toward the headquarters of the ruling party , police opened fire with tear gas . Opposition officials told CNN there were other peaceful demonstrations in towns in central and southern Tunisia . Tunisia 's unrest was triggered by the December suicide of an unemployed college graduate , who set himself ablaze after police confiscated the fruit cart that was his source of income . Recent diplomatic cables from the U.S. Embassy in Tunisia , disclosed by the WikiLeaks website , revealed growing discontent with what Tunisians believed was widespread corruption and nepotism within Ben Ali 's government . Experts say the kinds of protests seen in Tunisia could inspire similar actions , particularly by unemployed young people , in other Arab nations . In the weekend 's chaos , a group of Swedish hunters visiting Tunisia said Monday they were stopped on the streets near Kasserine and beaten . Some of the men 's eyes were swollen and blood-filled . One man had apparently been beaten on the back . Another man had a head injury . `` To be fair , when we look back , we can understand that our guns scared them , '' said one of the men , Ove Oberg , who met with CNN Monday morning . The men said by the time the army came and understood the hunters were tourists , they had been badly beaten . `` If the army did n't find us , we would have been dead , '' Magnus Josefsson said . Mohamed Guiga , a witness to Sunday 's clash between government troops and Ben Ali 's loyalists , said most Tunisians have rallied to each other 's aid since the uprising . `` We are proud of those people -- simple people , young people , normal people -- who take care of each other , '' Guiga said . CNN 's Rima Maktabi , Ben Wedeman , Per Nyberg , Matt Smith and Neil Curry contributed to this report .
