The terrorist threat still looms over Europe despite recent successes in eliminating terrorists linked to the deadly Brussels and Paris attacks, French President Francois Hollande said, Sputnik reported.
"We have had success in finding the terrorists and both in Brussels and in Paris there have been some arrests and we know there are other networks, because even though the one that carried out the attacks in Paris and Brussels is in the process of being wiped out - with a number of its members arrested - there is still a threat looming," Hollande said on Friday as quoted by NBC.
Earlier in the day, three suspects were arrested in Brussels during raids linked to the arrest of a suspected terrorist in France.
On Thursday, French police arrested Reda Kriket who was previously sentenced in absentia in Belgium for ties with terrorists.
Kriket, who was arrested in Argenteuil, a northwestern suburb of Paris, is likely an important member of a terrorist network, according to French Interior Minister Bernard Cazeneuve.
The arrests came after at least 31 people were killed and over 300 were injured in several terrorist attacks in Brussels on Tuesday. The Islamic State (ISIL, also known as Daesh) jihadist group, outlawed in a range of countries, including Russia, claimed responsibility for the attacks.
ISIL has also claimed responsibly for the deadly Paris attacks that took the lives of 130 people and injured some 350 in November 2015.
The Brussels attacks came days after police arrested Salah Abdeslam, a suspect in the Paris attacks.
