Four killed, nine injured in blast in Bolivia during Oruro carnival; three suspects arrested

La Paz: A bomb triggered a blast that killed four people during carnival celebrations in the Bolivian city of Oruro, police said on Thursday. Police commander Faustino Mendoza said a device packed with three kilograms of dynamite exploded late on Wednesday, killing bystanders. “We have four people killed and nine injured,” said Mendoza, adding that the blast occurred in a street near the scene of an even deadlier explosion on Saturday that killed eight people. Initially, a government minister said that explosion was likely caused by a street vendor’s gas cylinder.

Traces of ANFO, an industrial explosive widely used in the mining industry, were also found at the site of the latest blast, authorities said. President Evo Morales, in a statement on Twitter, said the South American country had been plunged into mourning. “Very saddened and concerned because we have a tragedy again, and the death of innocent bystanders in Oruro has our country in mourning after another explosion,” he wrote. The northwestern Bolivian city is known for its cobblestone streets and colourful carnival celebrations that attract as many as half a million visitors to the city. Thousands of people had danced along a four-kilometre circuit of streets during the festivities on Tuesday. On Thursday, the city’s university and schools located near the incidents remained closed.
