Bolivia's new president has ventured into the slum city at the heart of the country's popular revolt, appealing for calm one day after his predecessor resigned in the face of protests that claimed more than 70 lives.
President Carlos Mesa, elevated from vice-president after President Gonzalo Sanchez de Lozada stepped down on Friday, received a rousing welcome in El Alto, a ramshackle community of about 700,000 people overlooking La Paz.
"Never again should we lose a life through battles with the government," Mesa, addressing his first public rally since taking office, told a cheering crowd of about 1,000 people. The throng included old women in traditional bowler hats and young men waving the multicoloured Inca flag.
Under the constitution Mesa can serve until 2007 but he has asked congress to call early elections. He says his "gigantic task" is leading an interim government that prevents South America's poorest nation "sinking to the bottom."
He said "there would be no major changes" to Sanchez de Lozada's US-backed drive to wipe out coca leaf crops - the raw material for cocaine. But he pledged to negotiate with the peasant farmers who blame the policy for exacerbating their poverty.
El Alto was the focus of Indian-led protests against free-market policies that opponents say give Bolivia's natural gas resources to foreigners. Locals called the uprising, in which 74 people were killed, the "gas war."
Mesa, a respected journalist and political independent, appears to have escaped the resentment directed at his predecessor, a free-market advocate and US ally in the so-called anti-drug war.
Despite his role as Sanchez de Lozada's deputy and his membership of the traditional European-descended elite, Mesa has won at least a brief respite from protesters willing to give him time to prove himself.
Evo Morales, an Indian leader who came second last year in presidential elections and who symbolises the Indians' organisational strength, said: "I ask for calm ... until the government gets organised and meets the demands of society."
Mesa faces major obstacles - designated by congress to serve out the rest of Sanchez de Lozada's term, he has little electoral legitimacy and no formal political party support.
He promised to address Indian grievances, including holding a referendum on plans to export natural gas to the United States. Indian groups say the project will only benefit neighbouring Chile, the United States and foreign investors.
