Excerpt:
The BBC has apologised after a tweet from the Asian Network account asked, "What is the right punishment for blasphemy?".
The tweet provoked criticism that the BBC appeared to be endorsing harsh restrictions on speech.
In an apology posted on Twitter, the network said it intended to debate concerns about blasphemy on social media in Pakistan.
"We never intended to imply that blasphemy should be punished," it said.
The post on Twitter was intended to publicise the station's Big Debate programme with presenter Shazia Awan.
