"The move against Mr. Saeed, the founder of the banned militant group
Lashkar-e-Taiba, came amid a reported new round of pressure by the United States to arrest Mr. Saeed and to ban Jamaat-ud-Dawa, the charity he leads, which has been accused by American officials of being a front for militants. The News, a Pakistani English-language newspaper,
reported on Monday that American officials in the waning days of the Obama administration had threatened sanctions or other penalties if action was not taken."
