This shows the site of the Paris siege as well as this week's earlier attacks in the city:
An image of the supermarket currently under siege in eastern Paris, with an unknown number of people held hostage inside by a gunman.
It is still as yet unclear if there is a link between the two hostage situations. However, French media is quoting police sources as saying that the hostage-taker at the supermarket in Porte de Vincennes is making demands for the release of the two suspects wanted over the Charlie Hebdo attack, who are still engaged in a tense stand-off with police in Dammartin-en-Goele.
A meeting between French President Francois Hollande and the German Chancellor Angela Merkel, which was planned for Sunday in Strasbourg, is postponed amid the hostages crisis.

tweets:, external A reliable source has confirmed to the BBC that Cherif and Said Kouachi were on the UK Warnings Index "and had been for some time."
Hassan Nasrallah, the leader of the Lebanese Hezbollah group, has made a statement via video link, saying that Islamic extremists have insulted Islam and the Prophet Muhammad more than those who have published satirical cartoons mocking the religion.
He did not make a specific reference to the Charlie Hebdo attack in Paris but referred to Islamic State militants in Syria and Iraq, saying they had done more harm to Islam than anyone else in history.
Another eyewitness, named Golda, tells the BBC she was on her way to the supermarket under attack when she heard a "burst of gunfire". She sought refuge inside a nearby garage - where she has been holed up with several others for the last hour and a half.
"We can't really see what's on going at the supermarket because we can't see down there, but we are surrounded by the police and special forces," she tells BBC World TV.

The government says a crisis meeting has been called at the presidential palace in Paris about the hostage-taking. The meeting will be attended by President Hollande, Prime Minister Manuel Valls, Interior Minister Bernard Cazeneuve, and Justice Minister Taubira.
Arnaud Danjean, a former member of France's external intelligence agency, tells the BBC's Newshour programme it is close to impossible to keep an eye on all possible terror suspects.
"Of course, [the security forces] focus on the most dangerous people, [but] they cannot follow everyone. What is the case here is that these people - probably for a few years, at least for a few months, maybe for a few years - have disappeared or just were asleep. And reactivated very recently."
