Ecuador's public prosecutor has opened a terrorism investigation after at least five journalists received envelopes containing explosive devices.
Three of the envelopes reached the newsrooms of three separate television channels, while two other envelopes addressed to a radio station and journalist Carlos Vera were intercepted.
The public prosecutor says evidence has been collected from the media outlets that received envelopes containing the devices, and all the devices will be included in a single investigation due to the similarities between them.
On Monday, a TV journalist suffered minor injuries when he plugged a memory stick containing an explosive device into his computer.
The explosion did not injure anyone else, nor did it cause any material damage to the newsroom, located in the city of Guayaquil, southern Ecuador.
