Lionel Messi's father is undergoing medical treatment for an undisclosed illness and his family asked the media for "humanity" on Thursday amid rumors about Jorge Messi's health while his son competes at the World Cup.

The family did not specify the illness that the 68-year-old Jorge Messi is suffering from.

"Jorge is going through a health situation," the Messi family said in a statement. "He is currently under medical observation, recovering and progressing favorably within his current condition."

The 39-year-old Messi said after Argentina's 3-0 victory over Algeria in the team's opening World Cup match that he was going through a difficult personal situation. He was very emotional after scoring the first of his three goals, which allowed him to equal Miroslav Klose as the all-time leading scorer in World Cup history with 16 goals.

"My tears after the first goal? I've had some tough days. It wasn't related to soccer. And those feelings were because of that," Messi said. "I thank my teammates, the coaching staff and the delegation for helping me."
