A 48-year-old man and a 30-year-old man were arrested around 5.10am in Newport.
It came hours after a 25-year-old man was arrested at a different address in the city. Searches at the two addresses in Newport are ongoing.
Exclusive pictures obtained by ITV News showed the 25-year-old man surrounded by officers on the street after the arrest just after 7pm on Tuesday.
The arrests in Wales come after Friday's explosion in west London left 30 people injured.
An 18-year-old, believed to be the suspected bomber, was arrested at Dover's ferry port on Saturday.
A 21-year-old, believed to be Yahyah Farroukh, was arrested at a chicken shop in Hounslow, west London, also on Saturday. Both remain in custody.
Farroukh and the suspected bomber are believed to have spent time living with foster parents Penelope and Ronald Jones, aged 71 and 88 respectively, in Sunbury-on-Thames, Surrey.

We now have three men in custody and searches are continuing at four addresses. Detectives are carrying out extensive inquiries to determine the full facts behind the attack.
