Luci Bonnor, BBC Paris producer, says the Islamist flags and Molotov cocktails were found in the Citroen car abandoned on Wednesday after the shootings.
She adds: "In deliberately targeting and murdering journalists, the terrorists were attacking freedom and democracy. And in murdering police officers, they attacked the people who risk their own safety every day to protect us and our way of life."
UK Home Secretary Theresa May says: "The cowardly attacks that took place in Paris yesterday have shocked and sickened people in the UK and around the world. And they are a reminder of the very serious threat we face from terrorism."
It is unclear if Thursday's attack is linked to the Charlie Hebdo shootings.

Arab social media is abuzz with comment on the Charlie Hebdo attack. While most tweeters condemn the attack and voice solidarity with the victims, some have blamed the magazine for inciting hatred and "terrorism" through its caricatures. The English hashtag #CharlieHebdo has been a trending hashtag in many Arab countries. The Arabic hashtag of the magazine's name has been used to voice solidarity with the victims and in support of freedom of expression. It has been used over 27,000 times since the attack.
Nick emails: I really hope the French do not give those murderous thugs the easy way out by killing them. It would be much better to see them humiliated and dragged through the courts and exposed for what they really are, just savages who insult the name of Islam.
Paul Biggs emails: These criminals are not Muslims. They do not represent a fair minded faith. The devout Muslims I have met in my lifetime are very warm and caring people who have a deep faith, they are nothing like these inhumane animals. It is about time we stopped referring to them as Muslims and as "criminals". Thugs who have a gripe against society should not be listened or cowed to. Like all criminal acts, show them it has not worked and stand together, as we have done for so many years. As for satirical cartoons, freedom of speech is the greatest belief, please keep the faith.
Historian Tom Holland explains why he was one of those who tweeted Charlie Hebdo's cartoon of the Prophet Muhammad in the wake of the attack.
BBC Paris producer Luci Bonnor says the AFP news agency is reporting that sources close to inquiry say the abandoned car of the suspects contained jihadist flags and molotov cocktails.

French special forces are to be deployed in the north-east of France where the suspects were reportedly spotted, a police source tells Agence France Presse.

Divine Toonist: "From one cartoonist, to 4 others and everyone else who lost their lives yesterday... #JeSuisCharlie
Charlotte Patey in Reading emails: To fear or dislike being mocked is a sign of being insecure. It is not the same as being insulted. Je Suis Charlie.
Dr Shuja Shafi, secretary general of the Muslim Council of Britain, said: "Nothing justifies the taking of life. Those who have killed in the name of our religion today claim to be avenging the insults made against Prophet Muhammad, upon whom be peace. But nothing is more immoral, offensive and insulting against our beloved Prophet than such a callous act of murder. Our thoughts, prayers and solidarity go to the families of the victims and the people of France."
Neil Bourque emailed his cartoon: Drew this, this morning. Always wanted to be a cartoonist - now I do more than ever.
