Video footage obtained by Haaretz shows the Israeli protester who set himself on fire during a social protest in Tel Aviv on Saturday, speaking with a social activist  about his difficulty and disappointment with Israel's National Insurance Institute one month before his self-immolation.

In the video, Moshe Silman, told Haifa activist Omer Zengut that he would take part in Israel's social protest, saying, "If I am still alive, I will give my opinion."

Silman is currently suffering from second and third-degree burns on 94 percent of his body. Accoridng to Dr. Joseph Hayak, head of the burn unit at Sheba Medical Center in Tel Hashomer, he is still in very serious condition.

Early on Monday morning, vandals set fire to the entrance of a branch of the National Insurance Institute (Bituach Leumi) in Ramat Gan, in solidarity with Silman.

The words “Price tag Moshe Silman,” were written on the wall, referring to the man who set himself on fire during a protest in Tel Aviv on Saturday night.

Shortly after midnight on Monday, the fire department and police were called to the Ramat Gan branch of Bituach Leumi, on Hashmonaim Street.

Emergency services arrived on the scene to find the branch office’s entrance partly burned, and graffiti on the wall. Police have begun an investigation of the event.

Silman, a 57-year-old Haifa resident, has had various issues with the National Insurance Institute over the years.

On Sunday, protesters demonstrated in Tel Aviv, in a show of solidarity with Silman.

"Price-tag" attacks generally refer to operations conducted by settler extremists against Palestinian targets in the West Bank, in retaliation for moves perceived as anti-settler.

However, the use of the term in attacks within Israel proper is rare, especially against non-Arab targets.
