France has issued a maximum level of alert as police hunt a gunman who opened fire at a Christmas market in the eastern city of Strasbourg.
Three people were killed and 13 wounded, eight of them seriously.
The gunman, 29, known to authorities as having been radicalised in prison, escaped after reportedly being injured.
Some 350 officers are involved in the search for the gunman. The deputy interior minister has acknowledged he may no longer be in France.
Interior Minister Christophe Castaner said the country had issued an "urgence attentat" (emergency attack) alert, expanding police powers and creating the highest degree of vigilance.
He added that border controls had been strengthened and security at all Christmas markets would be stepped up.
The mayor of Strasbourg, Roland Ries, has said the Christmas market will be closed on Wednesday and flags lowered to half-mast at the local town hall.
Protests have also been banned in the city – which is the seat of the European parliament – but not in the rest of France, Reuters news agency said. The country is in the midst of a wave of protests highlighting the economic frustration and political distrust of poorer working families.
What happened?
The attack unfolded at around 20:00 local time (19:00 GMT) on Tuesday close to Strasbourg's famed Christmas market near one of the central squares, Place Kléber, which attracts thousands of visitors at this time of year.
There has been some confusion over the number killed in the attack. At one point, the figure was revised down to two by officials, but has since gone back to three./BBC
