London attack: Direct hand by ISIS unlikely, counterterrorism expert says

Khalid Masood was active on the encryption messaging service WhatsApp two minutes before he started his attack Wednesday on Westminster Bridge, but no evidence has emerged to show he was communicating with ISIS at any point, the official told CNN.

Investigators are looking into communications he had with individuals leading up to the attack that left four dead, including a police officer, the official added.
