Four people have been arrested in Ecuador in connection with the bombing attacks carried out along the Colombian border in the early hours of Wednesday, Interior Minister Cesar Navas has confirmed.
"There were police raids; as a result, four people were detained: three Ecuadoreans and one Colombian," Navas said during a news conference in Esmeraldas.
Ecuador's Ministry of Communications confirmed the early morning attack in the province of Esmeraldas, in northwest Ecuador, near a bridge in Viche. No injuries have been reported, but the explosive was professionally constructed, the minister said.
"The national government states that around 01:45 a.m. an explosion was registered around Viche, in the Quininde municipality of Esmeraldas. There were no victims, nor were any buildings damaged," the ministry said in a statement.
Police immediately deployed security measures, such as roadblocks and investigations by specialized teams.
The mayor of Quininde, Fabricio Tenorio, later said the roads have been reopened.
The province has been the target of a series of bomb attacks and kidnappings in the last few months, for which the Ecuadorean government has blamed drug cartels.
