Q: The unrest began when the start of voting was delayed because ballots and poll materials had not been delivered, and got worse after the discovery of stuffed ballot boxes, the UN official said. 
  
 Some 15 polling stations were set alight, a parliamentary candidate told AFP on condition of anonymity. 
  
 The town, in the central province of Kasai Oriental, is a stronghold for veteran opposition leader Etienne Tshisekedi, chief rival to President Joseph Kabila in Monday's national polls. 
  
 The UN source said Kananga residents had vandalised polling stations, blocked a truck from delivering election materials and thrown stones at a primary school where voting was due to take place after they found 190 ballot papers that had been hidden. ||||| KINSHASA Nov 28 (Reuters) - Masked gunmen opened fire with automatic weapons at a polling station in Lubumbashi, the capital of Democratic Republic of Congo's Katanga mining province, the governor of the province said as presidential elections took place on Monday.

 Voters in the Democratic Republic of Congo have begun casting ballots in presidential and legislative elections, after violence and accusations of fraud marred the run-up to Monday's vote. 
  
 The head of the country's electoral commission said Sunday there was no evidence of fraud, after at least one opposition candidate said vote tampering was under way favoring incumbent President Joseph Kabila. 
  
 At least three people were reported killed leading up to the election. 
  
 Police in the southeastern city of Lubumbashi said gunmen attacked two election vehicles early Monday and set them on fire. 
  
 This is only the second multi-party poll since the large central African nation was torn apart by two wars following independence. The last war ended in 2003. 
  
 Mr. Kabila, who is running against 10 opposition candidates, is widely expected to win re-election. Results are expected by December 5, the day before Mr. Kabila's current term ends. 
  
 President Kabila has been in power since 2001, when he assumed the presidency after the assassination of his father, Laurent Kabila. He won a presidential vote in 2006. 
  
 His strongest challenger, long-time opposition leader Etienne Tshisekedi, backed down from plans to hold a rally Sunday in the capital, Kinshasa, in defiance of a ban on campaigning the day before the election. His advisers say they feared for his safety. On Saturday, Congolese police blocked Mr. Tshisekedi and his supporters from leaving the airport for several hours. They fired bullets and tear gas, killing three and wounding several more. 
  
 The capital was reported calm on Sunday, described as a “Day of Reflection” in Congo, with no gatherings of large crowds. 
  
 Mr. Tshisekedi has accused the head of the United Nation's large peacekeeping force in Congo of a bias against him. He has called for removal of mission chief Roger Meece, who once served as the U.S. ambassador in the county. 
  
 More than 18,000 candidates are vying for 500 seats in the general assembly. ||||| AFP 
  
 An armed attack and long delays have marred voting in the Democratic Republic of Congo's national elections after a campaign that saw deadly violence. 
  
 Police in the southeastern city of Lubumbashi said armed men had swooped on a convoy of eight jeeps around 3am on Monday (Noon AEDT) and fled when police escorting the vehicles opened fire, wounding some of the assailants. 
  
 Two jeeps carrying nearly 1000 ballots caught fire and burned in the attack.

 The city, capital of the restive mining province of Katanga, had been a flashpoint of political violence in the run-up to the elections. 
  
 Earlier this month, two days of street fights between opposition and government supporters shut down parts of the city, as shop windows were shattered and pedestrians mugged. 
  
 On Sunday, gunmen attacked a military camp and arms depot in the city, killing one and fleeing after exchanging gunfire with soldiers. 
  
 It was not clear if either that raid or Monday's election convoy attack had any link to the partisan clashes during the campaign. 
  
 Violence also marred the run-up to the vote in the capital city of Kinshasa. 
  
 The last day of campaigning on Saturday descended into chaos as police banned all rallies, using tear gas, water cannons and live ammunition to disperse opposition supporters. 
  
 At least two people died in the unrest, although the exact circumstances were unclear. The campaign violence has drawn condemnation and calls for calm from the international community. 
  
 Incumbent President Joseph Kabila, 40, in power since 2001, is running for a new five-year term in the polls against a field of 10 challengers. 
  
 His main rival is veteran opposition leader Etienne Tshisekedi, 78. 
  
 The elections are only the second since back-to-back wars from 1996 to 2003, and the country remains one of the world's poorest, despite an abundance of cobalt, copper, diamonds and gold. 
  
 Though polling stations opened on time at 6am in some areas, there were reports of undelivered ballots and long delays in others. 
  
 Logistical headaches in organising the vote in a country two-thirds the size of western Europe - and whose roads network is crumbling and limited after seven years of war and decades of under-development - had raised fears the polls could be postponed. 
  
 The election commission had to bring in 81 aircraft to deliver 64 million ballot papers to some 64,000 polling stations across the country, in a process plagued by delays. 
  
 The run-up to the vote also saw allegations of fraud against the Independent National Electoral Commission (CENI), from opposition charges of "fictitious" polling stations to a leaked report by a consulting firm that said there were tens of thousands of ghost voters on the rolls. 
  
 As voting opened in the capital, small groups of voters waited outside voting office 10189 at the Saint Georges school. 
  
 The most senior official displayed the transparent ballot box, turning it upside down to prove it was empty at the start of the day. But, half an hour later, the lines of voters had not moved. 
  
 Rita, a 40-year-old mother of five, complained about the delay. 
  
 "The station hasn't even opened and it's 6.30," she said, adding that she planned to vote "for change". 
  
 "We need a president who loves this country. 
  
 "Those who are in power reap the benefits for their own interests, and for the others, the people - zero." 
  
 "I'm fed up. I'm voting for change," echoed 19-year-old economics student Jeremie. 
  
 "Even buying breakfast is hard for us in the Congo, especially in Kinshasa." |||||
A: 
Today’s presidential and legislative elections in the Democratic Republic of Congo have gotten off to a violent start. Reuters reports that masked gunmen fired on one polling station in Lubumbashi, while locals burned down three others in a neighboring province. The AFP reports 15 burned polling stations in that opposition stronghold, and notes the unrest began when voting was delayed and got worse when residents found stuffed ballot boxes. Also in Lubumbashi, the AFP reports that a convoy was attacked early this morning by armed men, some of whom were injured when police escorting the jeeps opened fire. Two of the vehicles caught fire, torching about 1,000 ballots. Lubumbashi, as well as the capital city Kinshasa, has seen significant violence in advance of the elections. Voice of America reports that at least three people have been killed in the unrest, and fraud allegations have flown. Incumbent President Joseph Kabila is expected to be re-elected.
