MOSCOW (Sputnik) — On Thursday evening, a heavy truck hit a crowd watching Bastille Day fireworks in southern France, killing 84 people and wounding dozens more. President Francois Hollande said the assault was of a "terrorist nature."
"Possible introduction of border controls can be done following the rules of the Schengen Border Code," the source said.
Nearly all EU member states are part of the Schengen system, established in 1995 to facilitate the free movement of people and goods within the bloc. However, in response to the migrant crisis, in the past months some EU member states have introduced strict border controls and toughened migration laws.
