France is stepping up security at the Belgian border, Interior Minister Gerald Darmanin said on Tuesday after the killing of two people by an assailant in Brussels the night before.
"We don't have information according to which he (the attacker) could be heading to France", Darmanin told RTL radio but France will as a precaution "double the number of security agents at the border".
Belgium was searching on Tuesday for a gunman who killed two Swedish citizens and wounded a third person on Monday in what the Belgian prime minister called a brutal terrorist attack that raised the terror threat level in Brussels to the maximum.
Brussels was again hit by an "Islamist terrorist attack," French President Emmanuel Macron said, speaking in Albania on Monday evening after a gunman killed two people in the Belgian capital.
"Europe is being shaken," Macron said.
