For the first time in Pakistan, Twitter blocks access to tweets which a government agency called "blasphemous and unethical".

Twitter has agreed to block some tweets in Pakistan which were regarded as "blasphemous" or "unethical".

Five requests were made by Abdul Batin, from Pakistan's Telecommunication Authority (PTA), who wants the microblogging site to censor accounts and tweets.

The objectionable posts included drawings of the Prophet Muhammad, photographs of burning copies of the Koran, and messages from a handful of anti-Islam bloggers.

Mr Batin said the posts were "blasphemous and unethical".

It is the first time the social network has agreed to block content in the country, according to a report in the New York Times (NYT).

Earlier this week a local edition of the NYT was printed with a blank space instead of an opinion piece headlined "Pakistan's Tyranny of Blasphemy."

Twitter has a country-specific censorship policy - unveiled in 2012 - meaning items blocked in one country will still be visible in another country.

Twitter has previously agreed to remove specific tweets in other countries to avoid having the entire network blocked.

In Germany it has withheld tweets of an outlawed neo-Nazi group, while an ultra-nationalist Ukrainian group's account was blocked in Russia.
