Belgian arrested two suspects and issued arrest warrants against three others following anti-terror raids Monday.
Investigators said earlier they had detained 16 people in the anti-terror raids after working with U.S. authorities to monitor suspects’ communications on WhatsApp Inc.’s messaging service.
So much for WhatsApp's supposedly secure end to end encryption. Obviously it is pretty much useless.
