Dutch and British revealing more evidence of Russian GRU attempt to hack into the OPCW - the independent body testing #Novichok

Hacking attempt disrupted on 13th April. Four Russian officers were escorted out of the country on the same day.

Dutch Defence Minister says this pubic disclosure is an "exceptional" step but is being done to hamper operations and send a message.

Now we will hear from the Head of Dutch Intelligence and Security Service (DISS):

10th April - four GRU agents arrive on diplomatic passports from Moscow.Met at Schipol airport by a diplomat from the Russian Embassy.

11th April - four men hire a car which is photographed tab the Marriott Hotel next to the OPCW. There for reconnaissance.

Equipment found in the boot of the Russian hire car. It was parked close to the OPCW with its boot facing the OPCW

Worth reiterating - at the time the OPCW was investigating the Skripal poisoning and chemical attack in Douma, Syria.

Head of Dutch Intel says: "Why were they not on holiday, sightseeing?"
* They had spy equipment on them.
* They took security measures like removing rubbish from hotel and putting it in the vehicle so remove traces.
* One was carrying 20,000 euros and $20,000.

One of the Russian officers had a taxi receipt that was from the street where the GRU is based to Sheremetyevo Airport in Moscow.

One of the laptops had data on putting it at scene of WADA in Lausanne and Kuala Lumpur close to the MH17 investigation.
