Leading the swift condemnation across the political spectrum of the overnight arson attack in the Palestinian village of Duma in the West Bank, in which a baby was killed and several members of his family injured, Israeli Prime Minister Benjamin Netanyahu declared : “I am shocked by this horrific, heinous act… This is a terror attack in every sense of the word. The State of Israel deals forcefully with terror, regardless of who the perpetrators are.”

Netanyahu said he directed the security services to use all means at their disposal to apprehend those responsible and bring them to justice.

“The government of Israel is united in its opposition to terrible and heinous acts such as these,” he said, adding that – speaking for the entire country – he wanted to send his condolences to the family of the baby killed in the attack and wishes for a speedy recovery to those injured.

Netanyahu requested that the Palestinian Authority be appraised of the steps being taken to apprehend the perpetrators.

18-month-old Ali Saad Dawabsha was killed in the fire, while her parents and four-year-old brother have been hospitalized. They were evacuated by Israeli helicopter to Tel Hashomer Hospital in central Israel for emergency treatment.

Nearby the scene of the crime, Hebrew graffiti was found proclaiming “revenge” and “long live the king,” accompanied by a Star of David emblem. It is thought that the arson was a so-called ‘Price Tag’ attack, acts of vandalism against Palestinian property by extremists opposed to curbs on settlement building.

Defense Minister Moshe Yaalon referred to the incident and the death of baby Ali Dawabsha as "a most severe terrorist act that we cannot tolerate, and we condemn in every way."

He noted that all security forces including the Shin Bet (Israel Security Agency), the IDF and police are carrying out a "supreme effort" to find those responsible, saying "we will pursue them until we get our hands on them."

"We will not allow Jewish terrorists to harm the lives of Palestinians across Judea and Samaria. We will fight them in every way, with every tool at our disposal."

He sent out his condolences to the Dawabsha family and requested restraint from the public "to allowing security forces to carry out their mission of capturing the murderers."

Opposition leader MK Herzog echoed a similar sentiment, calling the attack "a disaster--the worst kind of terrorism."

On his Facebook page, he added that this incident "requires national mourning." He also advised security officials to "increase vigilance and to investigate the incident with all the power available to them, including arrests and investigations to bring those responsible to justice as quickly as possible."

Jewish Home leader and Education Minister Naftali Bennett said “the murder of the baby is a shocking terror attack that is unfathomable,” while Knesset Speaker Yuli Edelstein addressed the perpetrators saying “We must ‘vomit’ these extremists from our midst.”

One day before, in Jerusalem an ultra-Orthodox man rushed a gay pride parade while wielding a knife, stabbing six people. Two received serious wounds.

Authorities say the perpetrator committed a similar attack 10 years ago.

The Israeli premier condemned the attack as "a despicable hate crime.” The stabbings were unrelated to the arson attack.

The Chief Rabbi of Jerusalem Aryeh Stern visited on Friday the victims of the stabbing attack, poke with them and denounced the attack as "totally contrary to the Torah" during his visit to the Hadassah Ein Karem hospital where the victims are being treated

"This is a day for prayer for the injured and for unity," said Stern.
