Celebrations marking Belgian National Day on July 21 will go ahead, but extra security is being planned after the Bastille Day attack in neighbouring France, Belgian Prime Minister Charles Michel said Friday.
The attack late Thursday in the southern French city of Nice follows two terrorist attacks in Paris and Brussels within the last eight months. Investigators have established several links between the perpetrators in those attacks.
There are no indications at present that Thursday's attack in Nice is connected to Belgium, Michel said in a press conference, according to the Belga news agency. Belgian security services are in contact with their French counterparts, he added.
Belgium is maintaining its security alert level at Level 3 - the second highest - Michel said, following a meeting of the country's national security council early Friday, the RTBF broadcaster reported.
The council includes police chiefs and intelligence services, as well as the country's coordinating unit for threat analysis.
"Level 4 implies concrete and precise information on a threat. But we don't have that type of information for the coming days in Belgium," he said. Measures for the July 21 celebrations will be "adapted," the premier added.
Belgian National Day is marked in Brussels each year with a military parade and activities in parks and squares across the city.
