A radio presenter was fatally shot by a man inside his southern Philippines station on Sunday in a brazen attack that was witnessed by people watching the programme live on Facebook.

The gunman gained entry to the home studio of provincial news broadcaster Juan Jumalon by pretending to be a listener.

He then shot the 57-year-old twice during a live morning broadcast in Calamba town in Misamis Occidental province, police said.

The attacker snatched the victim’s gold necklace before fleeing on a motorcycle with a companion, who had been waiting outside Mr Jumalon’s house, police said.

An investigation is under way to identify the gunman and establish if the attack was work-related.

The Philippines has long been regarded as one of the most dangerous places for journalists in the world.

President Ferdinand Marcos Jr strongly condemned the shooting and said he has ordered the national police to track down, arrest and prosecute the killers.

“Attacks on journalists will not be tolerated in our democracy and those who threaten the freedom of the press will face the full consequences of their actions,” he said in a statement.

The National Union of Journalists of the Philippines, a press freedom watchdog, said Mr Jumalon was the 199th journalist to be killed in the country since 1986, when democracy returned after a “People Power” uprising toppled dictator Ferdinand Marcos, the father of the current president, and forced him and his family into US exile.

“The attack is even more condemnable since it happened at Jumalon’s own home, which also served as the radio station,” the watchdog said.

A video of the attack shows the bespectacled Jumalon pausing and looking up at something away from the camera before two shots ring out. He slumps back in his chair as background music plays on.

He was pronounced dead on the way to a hospital.

The attacker was not seen on the Facebook livestream but police said they are checking if security cameras installed in the house and at neighbours’ homes recorded anything.

In 2009, members of a powerful political clan and their associates gunned down 58 people, including 32 media workers, in a brazen execution-style attack in southern Maguindanao province. It was the deadliest single attack on journalists in recent history.

While the mass killing was later linked to a violent electoral rivalry common in many rural areas, it also showcased the threats faced by journalists in the Philippines.

A surfeit of unlicensed guns and private armies controlled by powerful clans and weak law enforcement in rural regions are among the security concerns journalists face in the poverty-stricken Southeast Asian country.
