Twitter said it has deleted more than 125,000 accounts "for threatening or promoting terrorist acts" since mid-2015.
The micro blogging company, which has more than 500 million users, said most of the suspended accounts were primarily related to the Isis terror group.
"We condemn the use of Twitter to promote terrorism," the company said in a statement.
Twitter said it has asked its content review teams to act faster and that this has already seen results, "including an increase in account suspensions and this type of activity shifting off of Twitter."
Governments across the world have raised concern about social media sites unwittingly becoming propaganda machines for terror outfits and sympathizers.
Twitter accounts were handy tools for Isis militants in communicating with the public and followers and hiring radical activists.
US lawmakers have mooted a bill that requires Twitter and Facebook to report any apparent terrorist activity they find on their platforms.
Facebook revamped its community standards last year in the face of increased use of the platform for sharing extremist material.
"We remove content, disable accounts and work with law enforcement when we believe that there is a genuine risk of physical harm or direct threats to public safety," Facebook said.
According to Dave Lee, BBC's North America technology reporter, as many as 46,000 Twitter accounts were used to post extremist material in 2014. This number grew multifold in over year.
Recently, Google executive Jared Cohen discussed the idea of forcing Isis operatives into the dark web by denying them the 'public internet'. Another Google executive said the company was running a pilot algorithm that delivers wrong search results to jihadi sympathizers.
