Islamabad: It's a setback to 26/11 Mumbai terror attacks mastermind Hafiz Saeed.
Twitter has blocked 'HafizSaeedLive' account, which had frequent updates from the Jamaat-ud-Dawah chief.
The micro-blogging site apparently on its own took the action against the JuD chief.
The United Nations declared JuD a terrorist organisation and also individually designated Saeed as a terrorist in December 2008.
Saeed, who also has a US bounty of 10 million dollars on him, roams freely in Pakistan and often addresses public rallies in which he routinely makes inflammatory statements against India.
Pakistan has said that there is no case against Saeed and that he is free to move in the country as a Pakistani national.
India has repeatedly demanded Pakistan to hand over Saeed for questioning over his role in the 2008 Mumbai attacks that claimed 166 lives.
JuD was banned in 2002 by Pakistan but later a court lifted the ban due to lack of evidence on the group's involvement in militancy.
The group is also banned by the US, the EU, India and Russia as a terror organisation.
In June 2014, the US declared JuD a subsidiary of terror group Lashkar-e-Toiba.
