Unknown killers shot to death one of the bodyguards of Karina Rottman, the head of Guatemala's VEA Canal cable TV channel, which broadcasts news analysis and criticism shows, the channel said Sunday.

Rottman said that her bodyguard, identified as Viltor Garcia, was shot on Saturday night when near his home in an exclusive neighborhood on the eastern periphery of the capital.

Garcia, who died a few hours later in the emergency room of a public hospital in the capital, according to the TV channel, was attacked by unidentified gunmen riding in an automobile.

VEA Canal is noted for its analysis and criticism programs generally oriented against the administration of Guatemalan President Otto Perez Molina.

The channel allocates TV time to opposition, mainly leftist, leaders, who issue their commentary and critiques of the government.

Rottman, who hosts one of the channel's interview shows, said that this is the second attack against her security personnel in less than two weeks.

Two weeks ago, after meeting with Treasury officials in a capital restaurant, two of her bodyguards were beaten up by unknown attackers, she said, demanding that the authorities investigate and clear up the attacks.

So far this year, according to independent media outlets, there have been more than 80 attacks and threats against journalists in Guatemala. EFE
