Tshisekedi sworn in for second term as DRC president after disputed poll

Protests break out in two eastern cities as incumbent takes oath of office at stadium in Kinshasa

Felix Tshisekedi, the president of the Democratic Republic of Congo, has been sworn in for a second five-year term after a landslide victory his opponents have refused to recognise owing to widespread irregularities in the December general election.

Authorities have acknowledged there were problems but dismissed allegations the vote was stolen. The fractious standoff echoes previous electoral disputes that fuelled unrest in Africa's second-largest country, with protests breaking out on Saturday in two eastern cities.
