Belgium federal prosecutors said they have detained five more people following raids on Monday in the Brussels and Liege regions, reported Reuters. The authorities are hunting suspects linked to the November 13 terror attacks in Paris in which 130 people were killed. On Sunday, a total of 22 raids were carried out and 16 people arrested in anti-terror action in the country.

Suspected Paris attacks gunman Salah Abdeslam was not among those arrested, the authorities had said on Sunday, according to the BBC. The French-origin Abdeslam, 26, is believed to have played a key role in the Paris attacks.

In a separate development, The Guardian reported on Monday that British Prime Minister David Cameron has offered French President Francois Hollande the use of Britain’s Royal Air Force airbase in Cyprus to launch airstrikes against Islamic State militants in Syria.
