(BBC) Leaders of countries affected by recent terror attacks have voiced solidarity with the UK after the deadly attack near the Houses of Parliament.
A lone attacker was shot dead after he used a car to run down pedestrians, killing two, and stabbed a police officer to death outside Parliament.
Leaders of France and Germany, which suffered deadly vehicle attacks last year, offered the UK their support.
The US president offered condolences and praised UK security forces.
There is a mixture of nationalities among the dead, police say, and 29 people have been treated in hospital, of whom seven are critically injured.
Among those injured by the car on Westminster Bridge are three French schoolchildren and two Romanians, while five South Koreans were hurt in the chaos that followed the attack.
In Paris, the lights of the Eiffel Tower went out from midnight (23:00 GMT) in a tribute to the victims.
President Francois Hollande expressed his “solidarity” with the British people, saying “terrorism concerns us all and France knows how the British people are suffering today”.
In July last year, a man drove a lorry into pedestrians in the southern French city of Nice, killing 84 people. The attack was claimed by the Islamic State (IS) group.
German Chancellor Angela Merkel, whose country saw a lorry attack in December that killed 12 people in Berlin and was also claimed by IS, said her thoughts were “with our British friends and all of the people of London”.
“I want to say for Germany and its citizens: We stand firmly and resolutely by Great Britain’s side in the fight against all forms of terrorism,” she added.
US President Donald Trump spoke by phone to British Prime Minister Theresa May to offer his condolences and to praise the effective response of UK security services.
Mr Trump pledged the “full co-operation and support” of the US government in bringing those responsible for the attack to justice, the White House said in a statement.
Belgium’s prime minister sent a message of support as his country marked the first anniversary of the suicide bomb attacks on the Brussels airport and underground system, which killed 32 people.
“Our condolences are with those who mourn and all who are affected in London,” Charles Michel tweeted. “Belgium stands with UK in fight against terror.”
European Commission President Jean-Claude Juncker said in a statement that the people of Brussels and Belgium had “suffered a similar pain and felt the support of your sympathy and solidarity”.
“At this emotional time, we at the European Commission can only send that sympathy back twofold.”
Russian President Vladimir Putin also sent condolences by telegram to Mrs May, expressing support for the bereaved and wounded.
“The forces of terror are acting more and more deviously and cynically. It is clear that, in order to counteract the terrorist threat, all members of the global community must combine forces,” he said.
In other reaction:
- Canadian Prime Minister Justin Trudeau said in a statement that it was an “attack on democracies around the world” and Canadians stood “united with the British people in the fight against terrorism”
- Australian Prime Minister Malcolm Turnbull said it was an “attack on parliaments, freedom and democracy everywhere” and offered his support and solidarity to the British government.
- Chinese Premier Li Keqiang said he and Mr Turnbull had discussed the attack as they met in Canberra. “Together, we send our condolences to the prime minister of the UK and together we condemn terrorism and we stand against all forms of terrorism.”
- Dutch Prime Minister Mark Rutte said: “Horrible images from London. The very heart of the city has been struck. Our thoughts are with the British people.”
- Spanish Prime Minister Mariano Rajoy tweeted “solidarity with the victims”, and sent a telegram to Mrs May offering condolences. “We must remain united against these type of threats that affect all of us equally and that know no barriers,” he wrote.
- Turkish President Recep Tayyip Erdogan emphasised that “Turkey feels and shares deeply in the United Kingdom’s pain” and that it stood in “solidarity” with Britain “in the fight against terrorism”. It came just hours after his latest salvo in a fiery row with European allies, especially Germany and the Netherlands, over Turkish referendum campaigning in their countries. Mr Erdogan had warned that Europeans would not be able to walk safely on the world’s streets if “Europe continues this way”.
But not all international reaction was so reserved, with some right-wing politicians suggesting that controls on immigration – or even all Muslims – was the way forward. It has subsequently emerged that the attacker was born in Britain.
The leader of Australia’s One Nation party, Pauline Hanson, announced her own personal hashtag..
“It’s #Pray4Muslimban. Put a ban on it, that’s how you solve the problem, and then let’s deal with the issues here,” she said.
“We’ve got real problems… make sure that we do not have this religion which is really an ideology that is going to eventually cause so much havoc on our streets, not only for ourselves, but for future generations.”
In France, National Front leader Marine Le Pen, who is campaigning for the French presidency, said the London attack showed the need for borders to be protected.
She told French media that security measures needed enhancing amid a rising threat from “radicalised personalities who act alone without networks”, and urged countries to co-operate with each other on sharing intelligence.
Poland’s Prime Minister Beata Szydlo said the London attacks justified the country’s policy of refusing to take in refugees.
“I hear in Europe very often: do not connect the migration policy with terrorism, but it is impossible not to connect them,” she told private broadcaster TVN24.
