Intelligence sharing 'is key' as Europe faces terror threat

With Europe facing a fresh terror threat after three bomb blasts killed at least 34 people and injured about 270 in the Belgian capital on Tuesday, analysts agreed that sharing intelligence was at the heart of combating extremist groups such as Islamic State, which claimed responsibility for the Brussels attacks.

Anthony Glees, a professor at the University of Buckingham in London and director of its Centre for Security and Intelligence Studies, told China Daily that Belgium's divided society made it easy for terror groups to slip into that country unnoticed.

He said the Brussels attacks on the main airport and a rush-hour subway train came as no surprise, given last week's arrest in Brussels of Salah Abdeslam, a key suspect in the November terror attacks in Paris that killed 130 people.
