LONDON: World leaders responded to Friday’s bloody attacks in Paris with outrage and defiant pledges of solidarity, but several countries said they would tighten security, especially at their borders, and a few urged their citizens not to travel to France.

Several countries said they had stepped up their own security in response to the attacks, including Belgium and Switzerland, which border France. France’s neighbour to the south, Spain, said it was maintaining its state of alert at level 4 on a five-point scale.

Dutch Prime Minister Mark Rutte said the Netherlands would tighten security at its borders and airports, and said the Dutch were “at war” with the self-styled Islamic State.

“Our values and our rule of law are stronger than their fanaticism,” he said.

Belgium imposed additional frontier controls on road, rail and air arrivals from France and Belgian Prime Minister Charles Michel asked Belgians on Saturday not to travel to Paris unless necessary. Hong Kong also issued a travel alert for France.

Bulgaria imposed additional frontier controls on road and transit traffic.

London Metropolitan Police Service’s assistant commissioner Mark Rowley told the BBC that policing across Britain would be strengthened but said there would be no change to the threat level which currently stood at the second-highest category.

New York, Boston and other cities in the United States bolstered security on Friday night, but law enforcement officials said the beefed-up police presence was precautionary rather than a response to any specific threats.

The United States and Russia, divided on many issues including the war in Syria that has fuelled Islamist violence, voiced their support for the French people on Friday night.
