Renewed access to the site may not last since the Turkish government can appeal the ruling, says Hurriyet Daily News.
Threat came after allegations of corruption within the leader's inner circle spread across social networks.
Prime Minister Tayyip Erdogan says that a court order lifting the Twitter ban should be overturned.
After Prime Minister Tayyip Erdogan instituted a ban -- “wiping out” the social network -- the country’s constitutional court says not so fast.
The Turkish prime minister may have ordered the tap turned off, but citizens are still sneaking their tweets into the Twittersphere.
The ruling paves the way for most of YouTube to come back online, but 15 specific videos will still be blocked, according to Reuters.
The ban has officially been lifted, a Turkish government official confirms to Reuters.
The move comes just a week after authorities took similar action against Twitter, as the country's prime minister faces growing criticism for limiting free speech.
Accounts linked to the spread of government corruption allegations appeared blocked less than a week after the social network agreed to shutter some accounts.
Prime Minister Recep Tayyip Erdogan still has it in for the site, after it was used to spread information critical of him and after a Turkish court ruling led to a ban being lifted.
