The BBC is the latest victim of a Twitter hacks as the corporation reports that several of its feeds have been compromised.
A group identified as the Syrian Electronic Army took over the Beeb's weather, Arabic and Radio Ulster feeds with several fake tweets appearing on Thursday afternoon.
The BBC has said it is aware of the hack and is working on a fix. But the breach is the latest of several high-profile Twitter hacks in recent weeks - Burger King and Chrysler were other companies affected.
Fake weather conditions in several countries were posted by the group, which has previously shown support for Syrian President Bashar-al-Assad.
"We are aware that in the past few hours several BBC Twitter accounts have been hacked. We are actively working on this and expect it to be resolved shortly," said a BBC spokesperson.
Twitter hasn't yet commented on the hack, but the social network is coming under increasing pressure to boost security around the site.
"People and organisations need to take more control of their online experience and personal information - particularly when browsing the web from unsecured wireless networks," said David Gorodyansky, founder and CEO of AnchorFree.
"One easy step is to use a personal VPN like Hotspot Shield to encrypt your browsing and data traffic. The BBC, for its part, should be educating online users on how to protect their identity, not succumbing to the threats itself.”
