Qatar-based broadcaster Al Jazeera said the Twitter account for its main Arabic-language channel was temporarily "suspended" on June 17, in the latest incident at the station."Most of our Arabic accounts were blocked, but they are now up-and-running," the spokesman told AFP, adding that it may take several hours for them to be fully restored.
An investigation was taking place to determine the cause, and technical teams from the broadcaster were trying to coordinate with Twitter.
Al Jazeera’s main Arabic language account has almost 12 million followers.
The station’s English-language account was unaffected.
The announcement that the online accounts were back came around an hour after first reports that some of Al-Jazeera’s Twitter accounts had been blocked.
"Disruption (by others) will not stop because the truth terrifies them. We’ll be back."
The incident came at a time of diplomatic crisis between Qatar and neighbouring Gulf countries.
All diplomatic ties with Doha were cut on June 5 by several countries including Saudi Arabia, Bahrain, Egypt and the United Arab Emirates, which accuse Qatar of supporting and funding Islamic terrorist groups.
Qatar strongly denies the charge and claims those countries which have cut links are trying to change Doha’s foreign policy.
The television channel has long been a target for criticism by other Middle East countries, with Al Jazeera banned on several occasions.
Earlier this month, Al Jazeera said it was combatting a large-scale cyber attack.
