“I received with great sadness the news of the death of Dalia Elyakim in the horrific terror attack in Berlin,’’ said Israeli President Reuven Rivlin said in a statement.

The Israeli woman, who was vacationing with her husband in the German capital, was discovered dead on Thursday morning.

She was missing since Monday’s terror attack in Berlin when a truck ploughed into a Christmas market, killing 12 people.

Elyakim's husband, Rami, was seriously injured in the attack and remains hospitalized after recovering from surgery.

In his message, President Rivlin also said : ‘’From here I send my sympathies and offer strength to her family who are by the bedside of her husband Rami, who was seriously injured in the attack, and we pray for his speedy recovery.’’

He added : ‘’ We will remain united and determined in the face of this murderous terror which strikes across the world, and we will fight relentlessly against extremism and hatred.”

The 25-ton truck, belonging to a Polish freight company, smashed into wooden huts serving mulled wine and sausages, also injured about 45 people.

Terror group Islamic State has claimed responsibility, as it did for a similar attack in July when a Tunisian-born man rammed a truck through a crowd celebrating Bastille Day in the southern French city of Nice. Eighty-six people were killed, and the driver was shot dead by police.

German police are currently looking for a Tunisian man, described as "armed and dangerous," after finding an identity document under the driver's seat of the truck.

The document was in the name of Anis Amri, born in the southern city of Tataouine in 1992. The man is also believed to use false names, according to a statement released by German authorities.
