Iranian authorities have restored access to Gmail one week after blocking Google's popular email service in the country.
But reports from Tehran say a government Internet committee is still working on new censorship measures against the Google-owned YouTube video-sharing website.
Iran blocked Gmail last week in response to video clips posted on YouTube of an anti-Islam film that set off deadly protests across the Muslim world.
The Gmail ban sparked complaints from Internet users and officials in Iran.
On October 1, Mohammad Reza Aghamiri, a member of the governmental Internet watchdog committee, told the semiofficial Mehr news agency that authorities had lifted the Gmail ban after resolving technical problems to separate YouTube and Gmail.
YouTube was still being blocked in Iran by midday.
