Four people have been killed and at least ten injured in clashes between supporters and opponents of leftist President Daniel Ortega, who was re-elected in a weekend vote in Nicaragua.
Police spokesman Fernando Borge told reporters that the clashes took place Tuesday in two separate events in towns in northern Nicaragua.
An Ortega supporter was killed in a clash in the town of Siuna, while three members of the right-wing Independent Liberal Party were killed in San Jose de Cusmapa, Mr Borge said.
All four people died from bullet wounds, he added.
Mr Ortega won re-election Sunday with 60% of the vote in polls that also gave his Sandinista National Liberation Front (FSLN) a majority broad enough in the unicameral legislature to change the constitution.
The results were immediately contested by his two main rivals, Fabio Gadea, who came in second, and former president Arnoldo Aleman, both of whom charged fraud.
Foreign electoral observers also raised questions about the process.
