The Polish Consulate General in Lyon appealed to Polish citizens on Thursday to avoid the vicinity of the Notre Dame Basilica in Nice, France, and to follow the advice of the local authorities after an attacker killed three people and injured several others in the city in the morning.
The area around the Notre Dame Basilica was cordoned off by police. Witnesses spoke of panic breaking out as a result of the attack, which took place during a raised terror-threat level.
In response to the attack, the head of the French Ministry of Home Affairs launched a crisis unit. The Elysée Palace announced that President Emmanuel Macron will travel to Nice on Thursday.
Polish diplomats in Brussels have expressed their solidarity with France after the attack.
"We are deeply shocked and saddened by the news of the horrific terrorist attack in Nice. We express our solidarity with the victims, their families and all those affected by the tragedy", the Permanent Representation of the Republic of Poland to the European Union wrote on Twitter.
Polish President Andrzej Duda has also sent a message of condolence to his French counterpart Emmanuel Macron.
"I received with great sadness the shocking news of the brutal murder of three defenceless people in the Basilica of Notre-Dame and its vicinity. Nothing can justify this act of inhuman barbarism," he wrote in the message.
"Please express my deepest sympathy to the relatives of the victims. We keep them in our thoughts and prayers", added the president.
