Twitter says it shut nearly 377,000 accounts for promoting terrorism in the second half of last year.
This is a large increase on the last numbers given by the company, which covered from February to August 2016, although the data overlaps.
Twitter has faced pressure to do more to stop groups such as so-called Islamic State from using its platform.
Twitter said that 74% of the accounts it had suspended had been “surfaced” by internal, proprietary spam-fighting tools.
It also said it had shut a total of 636,248 accounts for promoting terror since August 2015, when it first began tracking numbers.
That is up from a total of 355,000 reported last summer.
