Cameron also offered the use of a British air base in Cyprus for anti-Daesh actions in Syria.

Speaking in Paris on Monday after meeting French President Francois Hollande, Cameron said the two leaders agreed to increase counterterrorism cooperation after the attacks.

He called for greater European Union-wide efforts to share intelligence to stop terrorist.
