The Arabic-language account of Al Jazeera has been restored on Twitter after being suspended due to what the network called "an organised campaign".
The account, with just under 12 million followers, was suspended for an unspecified reason early on Saturday.
Al Jazeera is the flagship broadcaster for Qatar, which is under pressure from its Gulf neighbours. They accuse the emirate of links to terror groups.
The account was restored by early afternoon Qatar time.
Twitter's rules state that an account can be suspended for three main reasons: because it is posting spam, because it has been hacked or compromised, or because it "engages in abusive behaviour, like sending threats to others or impersonating other accounts".
