'Black Friday for France'

France's Jewish community was among the targets of the last attacks Paris in January and Israeli Prime Minister Benjamin Netanyahu added his voice to the condemnation.

"Israel stands shoulder to shoulder with French President Francois Hollande and with the people of France in our common battle against terrorism," he said.

Netanyahu told France's Jewish community -- the largest in Europe and one of the largest in the world -- after the January attacks on Charlie Hebdo magazine and a Jewish supermarket that they would be welcomed with open arms by Israel.

President Recep Tayyip Erdogan of Turkey, where twin bombings on a peace rally in Ankara last month killed 102 people, offered his condolences.

"As a country that knows very well the manner and consequences of terrorism, we understand perfectly the suffering that France is experiencing now," he said. 

European Union foreign policy chief Federica Mogherini tweeted that she was "in the process of following with pain and dread the events in Paris". 

"Europe is with France and the French people," she said.

Angela Merkel, the chancellor of neighboring Germany, said she was "profoundly shocked by the news and images from Paris", while Dutch Foreign Minister Bert Koenders tweeted: "Shocked and appalled by new attacks in #Paris. Words are not enough."

And in Australia, where a lone gunman reportedly shouting Islamist slogans killed a man outside police headquarters in Sydney last month, Foreign Minister Julie Bishop said "this is indeed a black Friday for France and for the world".
