A pro-Islamic State group twitter handle on Tuesday praised the Brussels terror attacks that left at least 28 dead and dozens wounded.
A tweet re-tweeted by Terror Monitor group read: "What a pleasure to explode an unfaithful head and even better to cut his head."
It threatened more attacks: "Expect more bombs, more death! in future also."
Two explosions rocked the Zaventem airport in Brussels killing 13 people. A third explosion followed at a Metro station in the heart of the Belgian capital, claiming 15 more victims.
Scores were also injured in the coordinated attacks -- only four days after Belgian Police arrested the suspect in the Paris terror attack which killed 130 people in November.
