Colombian Senator Miguel Uribe Turbay was shot in Bogota on Saturday, according to the government and his party, with no immediate confirmation from the authorities on the status of his condition.

The 39-year-old senator is a member of the opposition conservative Democratic Center party, founded by former Colombian President Alvaro Uribe. The two men are not related.

According to a party statement condemning the attack, the senator was hosting a campaign event in a public park in the Fontibon neighborhood in the capital on Saturday when “armed subjects shot him in the back.”

The party described the attack as serious, but did not disclose further details on his health.

Colombia’s presidency issued a statement saying the government “categorically and forcefully” rejected the violent attack, and called for a thorough investigation into the events that took place.

Uribe’s mother, the journalist Diana Turbay, was killed in 1991 during a rescue operation after she was kidnapped by Pablo Escobar’s Medellin cartel.
