An Israeli tourist is among the injured in Monday’s terror attack in the center of the German capital.

Twelve people were killed on Monday evening when a truck ploughed into a Christmas market near the Kaiser Wilhelm Memorial Church. At least 48 people were seriously injured.

The injured Israeli tourist was in the market with his wife, who is still missing, Elio Adler, a family friend in Berlin, told JTA. The husband was located in a Berlin hospital, where he is currently undergoing emergency surgery. The wife has not yet been located.

A memorial service has been planned by Chabad in Berlin, for Wednesday evening.

Dr. Moshe Kantor, President of the European Jewish Congress, said: “We are appalled at these senseless and despicable murder across Europe”.

“Our hearts are with the victims and their families, our deepest solidarity with the people and our strongest wishes for a full recovery to those injured in these barbaric attacks.”

“Once again we have seen the bloody face of Islamist terrorism in our capitals and in our streets. Let us not just hope that 2017 will be a better year, but let us join together to defeat this scourge and rid it from our societies.”

Chabad Rabbi Yehuda Teichtal, a rabbi in Berlin’s official Jewish community, told JTA that he had been to the scene of the attack on Monday night with colleague Rabbi Shmuel Segal to see if they could help. Teichtal told JTA that plans for the annual public menorah lighting ceremony at Berlin’s famous landmark, the Brandenburg Gate,  would go ahead as planned, albeit with higher security.

Teichtal said he hoped that “more people than ever” would come to the event. “We have to have zero tolerance for terrorism and at the same time reach our hands out.”

Expressing sorrow for the victims and their families, Berlin Jewish Community head Gideon Joffe said that Berliners are proud of their tolerant and cosmopolitan city and would fight to keep it that way.

“We can’t let terror determine our lives,” he said, adding that he urged all Berliners to come to the Chabad candlelighting ceremony on Dec. 27, “especially in times like these.”

According to local news reports, the Polish driver of the truck was shot and killed. Police arrested one suspect after he tried to flee on foot. He reportedly came to Germany from Pakistan more than a year ago.

Early Tuesday afternoon police announced that the arrested man was not the driver in the deadly attack and that he had been released. Police also said that there is a possibility that the suspected perpetrator remains armed and running loose in the city and called on residents not to go out.

The truck was driven about 80 meters through the Christmas market,  which was filled with holiday shoppers. Berlin police said they believe the incident was not an accident.

The Central Council of Jews in Germany in a statement called the attack “disgusting” and added: “Our thoughts and actions must not be overcome by fear and terror…May the messages of our two holidays give us strength in these difficult hours.”

“We are deeply shocked. Especially in the pre-Christmas period, when our society focuses on values like charity, goodness and peace, our country was once again hit by this disgusting attack,” the group’s statement attributed to President Josef Schuster said.

Israeli Prime Minister Benjamin Netanyahu in a statement issued Tuesday condemned the attack and sent condolences to the families of the people killed and the government of Germany.

“This attack joins [other] reprehensible attacks; terror is spreading everywhere and can be stopped only if we fight it, and we will defeat it, but we will defeat it much quicker if all free nations under attack unite,” Netanyahu said.
