"LeT was responsible for the May 23, 2014, attack on the Indian Consulate in Herat, Afghanistan," the State Department said today while announcing additional sanctions against LeT affiliates and leaders.
The attack on the Indian Consulate in Herat on May 23, three days before the swearing-in ceremony in New Delhi on May 26.
On the eve of the swearing-in ceremony, Afghan President Hamid Karzai had told an Indian news channel that LeT was responsible for the terrorist attack.
The Indian consulate in Herat was attacked on May 23 by four heavily-armed gunmen, who were subsequently killed in an encounter as India attributed the pre-dawn strike to terror elements "beyond the borders" of the war-torn country.
Since its inception LeT has been focused on carrying out major terrorist attacks inside India.
LeT claimed responsibility for the 2008 Mumbai terrorist attacks that killed at least 166 people.
In 2011, LeT was responsible for multiple terror attacks, mostly in Jammu and Kashmir, and in 2012, LeT claimed responsibility for an attack against an Indian army convoy in Kashmir that killed one civilian and injured two others, the State Department said.
LeT was designated as a terrorist organisation in December 2001.
Since the original designation, LeT has repeatedly changed its name in an effort to avoid sanctions.
More specifically, LeT created Jamaat-ud-Dawa as a front organisation, claiming that the group was an "organization for the preaching of Islam, politics, and social work", the State Department said.
Al-Anfal Trust, Tehrik-e-Hurmat-e-Rasool ('Movement for Defending the Honor of God'), and Tehrik-e-Tahafuz Qibla Awwal ('Movement for Safeguarding the First Center of Prayer') are also LeT front organizations, since at least 2011, LeT has used Al-Anfal Trust to procure goods from the Persian Gulf, it said.
