BERLIN, May 24 (Xinhua) -- German police arrested four Islamists after a raid in Berlin on early Wednesday.
The police said they have already issued arrest warrants for three of the arrested and the other one will be brought for investigation.
They were allegedly "violent Islamists," local media Focus Online reported, citing the police and prosecutors.
The Berlin Police as well as some special forces carried out an anti-drug operation early Wednesday, raiding six targeted addresses in Neukoelln, Koepenick, Mariendorf and Zehlendorf.
Drugs and some weapons were seized, and a total of 9 people were taken into custody, among them, the four Islamists.
The raid was made at a time when Berlin state government was under public pressure. Earlier in May, German interior ministry pointed out that Berlin government could have prevented last year's terror act on Berlin's Christmas market, which killed 12 people and injured over 50.
It was disclosed that Berlin had sufficient evidence to arrest the attacker, Anis Amri, on drug charges weeks before he drove his truck into the crowds.
