Mahmud Ali Durrani, Adviser to the Prime Minister on National Security, said if evidence was found of the Jamaat being involved in the attacks, it would be banned.
Durrani told Geo News channel that if any evidence pointed to any other organisation during investigations, they too would be banned.
His comments echoed remarks by Pakistan's UN Ambassador Abdullah Hussain Haroon that the Jamaat could be banned and its assets frozen on the request of the UN Security Council.
Hussain made the remarks after India asked the UN Security Council to "proscribe the Pakistani group Jamaat-ud-Dawah since it is a terrorist outfit and should be proscribed under Security Council Resolution 1267."
Security Council Resolution 1267 imposed sanctions on supporters of al-Qaeda, Osama bin Laden and the Taliban. Individuals and groups banned under the measure face travel bans and asset freezes.
Speaking to reporters in Multan on Wednesday, Prime Minister Yousuf Raza Gilani indicated that the government believed the Jamaat was a front organisation for the LeT.
"The LeT is a banned group. If its members become part of the Jamaat-ud-Dawah, what will be its status?"
He, however, said the recent crackdown on the Jamaat did not come because of Indian pressure and the US had had concerns about the group since 2002.
