An alleged gunman was charged by authorities today for the attempted murder of Slovak Prime Minister Robert Fico revealing that the shooting was ignited by the election win of a Fico ally back in April. 

"This is a lone wolf whose actions were accelerated after the presidential elections since he was dissatisfied with its outcome," Interior Minister Matus Sutaj Estok said.

According to the media, the suspected gunman, who was arrested on the scene is a 71-year-old writer. 

The suspect was charged with attempted murder today. 

Speaking with the Slovak news site aktuality.sk, his son said that he had "absolutely no idea what father was thinking, what he was planning, why it happened".

The Fico ally who won April's vote, Slovak president-elect Peter Pellegrini urged earlier today for calm calling on political parties to stop campaigning for June's EU parliament election. 

Fico's condition stabilized but 'very serious': Slovak Deputy PM

Slovak Prime Minister Robert Fico's condition has stabilized overnight but is still "very serious", the deputy prime minister said today, a day after Fico was shot multiple times.

"During the night doctors managed to stabilize the patient's condition," said Robert Kalinak, who is also the Defense Minister, adding, "Unfortunately the condition is still very serious as the injuries are complicated."

Tomas Taraba, another deputy, told the BBC he believed Fico's hospital procedure had gone well.

"I guess in the end he will survive," Taraba said. "He's not in a life-threatening situation at this moment."

Earlier, Interior Minister Matus Sutaj Estok told reporters at a hospital in the central city of Banska Bystrica that the 59-year-old leader was "in critical condition and his life is in danger."

Police detained a suspect at the site of the attack in Handlova, President Zuzana Caputova told reporters.

According to the Pravda news agency, Slovak Prime Minister Robert Fico suffered an injury after he was shot at the location of the government's field meeting on May 15, and the assailant was captured.

The assailant fired five times before police apprehended him, Pravda reported. 

Slovakian former Prime Minister Robert Fico won the parliamentary elections in October, claiming a 5% support lead over his main rival, as the United States and its allies are increasingly finding it difficult to justify more international and public support to Kiev - even among their own countries - amid underwhelming field performance.

His socialist political party Smer landed nearly 24% of the votes - granting him 42 seats out of 150 in the legislative assembly - while the liberal Progressive Slovakia party garnered around 17%.
