Prime Minister Māris Kučinskis condemned the attack that claimed dozens of lives as further details are emerging.
"We have to be more united than ever and support one another. Such barbaric acts of terror should not be allowed to happen, and we will do everything to prevent them from happening again," said Kučinskis via the State Chancery.
He also took to Twitter to express his response.
"I strongly condemn the terrorist attack in France and express the deepest condolences to the victims' relatives and the French people. We're together with France in sorrow."
Asi nosodu Francijas teroraktu un izsaku dziļāko līdzjūtību bojāgājušo tuviniekiem un visai Francijas tautai. Sērās esam kopā ar Franciju.— Maris Kucinskis (@MarisKucinskis) July 15, 2016
While President Raimonds Vējonis extended condolences to the families and relatives of those killed and wished speedy recovery to the people injured in the attacks.
He said via the President's Chancery that the terrible act of terror is an attack not only on France but on Europe, urging European countries to join in fighting terrorism.
The Foreign Ministry echoed the words of President Vējonis in saying that Latvia stands united with France. However it also urged closer cooperation between security services.
"Latvia strongly condemns terrorism and turning against civilians. Terrorism has no national, ethnic or religious borders. Its goal is to spread fear and distrust. The events once again confirm the need for tight and coordinated cooperation between the responsible authorities in the European countries, as well as the need for information exchange, including with third countries," the ministry said.
No Latvians have yet been identified among the victims of the attacks, Foreign Ministry spokesman Raimonds Jansons told Latvian Television. The ministry advises travelers to France to be aware of raised security and tightened border controls as French President Francois Hollande has extended the state of emergency across the country.
The ministry also provided a reminder that Latvians abroad can call a special emergency hotline:
Ja atrodaties Nicā un ir nepieciešama konsulārā palīdzība zvaniet uz Ārlietu ministrijas diennakts tālruni ārkārtas situācijām +371 26337711— Ārlietu ministrija (@Arlietas) July 15, 2016
Latvian Radio observed people on Friday morning laying flowers by the French Embassy, much like after the most recent attacks last November.
A bystander said "It's impossible that one can do such a thing on a festival day, that people are dying, that children are dying."
Even though the identity of the person carrying out the attack is yet to be confirmed, National Alliance MP Jānis Dombrava on Twitter was quick to link it to immigration.
"And I say this again. Immigration is a threat to Europe and it must be stopped. I express my condolences to the relatives of the people who've been killed."
Un atkal saku šos vārdus. Imigrācija ir drauds Eiropai un tā ir jāaptur. Izsaku līdzjūtību noslepkavoto cilvēku tuviniekiem.— Jānis Dombrava (@janisdombrava) July 15, 2016
