WASHINGTON: The US Treasury Department is taking action against individuals and networks linked to militant groups Lashkar-e-Taiba and Harkatul Mujahideen.

Treasury's action on Tuesday targets the leader of Harkatul Mujahedeen, which is known to maintain training camps in eastern Afghanistan.

Treasury also slapped terrorist designations on two people and their networks for allegedly working to provide financial support to Lashkar-e-Taiba.

The action freezes any assets they might have in any US jurisdiction and bans US citizens from doing business with them.

David Cohen, undersecretary for terrorism and financial intelligence, says both groups are violent terrorist organisations that train militants and support extremist groups, including al Qaeda.

Last month, the US Treasury Department imposed strict sanctions on a founding member of the LeT and has also banned his currency exchange business.

The Treasury identified Muhammad Iqbal of Lahore as a founding member of the governing board of Falah-i-Insaniat Foundation, declaring the Foundation a Lashkar affiliate which collects funds for the group.

In a display of solidarity with India earlier in August, the US equated LeT with al Qaeda, urging Pakistan to bring the perpetrators of the Mumbai terrorist attacks to justice.

LeT was blamed for the 2008 attacks by Pakistani gunmen in Mumbai which killed 166 people and triggered a complete breakdown in ties between New Delhi and Islamabad.
