Police are reportedly examining what appeared to be Molotov cocktails found in the van used in the London Bridge attack.
At least 12 homemade explosive devices were found inside the vehicle that rammed into pedestrians on Saturday night, according to Sky News. The fire brigade were reportedly present when the devices were removed.
The bottles were reportedly filled with clear liquid and had rags stuffed in their tops.
Police earlier named two of the three perpetrators of the attack, who were shot dead by police just eight minutes after the first call to emergency services.
Khuram Shazad Butt and Rachid Redouane, both from Barking in east London, were identified as two of the three homegrown terrorists. A third man has not yet been named by authorities.
Pakistan-born British citizen Butt, 27, had previously appeared in a Channel 4 documentary called The Jihadi Next Door and was known to police and MI5. Redouane, who had claimed to be Moroccan and Libyan and also used the name Rachid Elkhdar, was not known to British authorities.
A third man has not yet been named by police.
All three were shot dead at the scene of the attack within eight minutes of the first 999 call.
