US Army psychiatrist Nidal Hasan, paralysed from waist down due to bullet wounds received during his shooting spree that killed 13 fellow soldiers, may have wired money to Pakistan which could lead to his possible links to militant groups there, according to two Congressmen.

Citing Congressman Pete Hoekstra, the Ranking Member of the House Intelligence Committee, 'The Dallas News' reported about 39-year-old Major Hasan's possible connections to Pakistan.

"Republican Pete Hoekstra, said sources 'outside of the (intelligence) community' learned about Hasan's possible connections to the Asian country, which faces a massive Islamist insurgency and is widely believed to be Osama bin Laden's hiding place," the paper said.

Hoekstra, the daily said, would not identify the sources. But, it said "they are trying to follow up on it because they recognise that if there are communications, phone or money transfers with somebody in Pakistan, it just raises a whole other level of questions."

Another Republican Congressman Michael McCaul, a member of the House Homeland Security Intelligence Subcommittee, also said that "independent sources" had confirmed the Pakistan link, but declined any details about the source of the information.

"In addition to the e-mails to (Anwar-al-Awlaki) the Imam in Yemen, I have confirmed through independent sources that there were communications and wire transfers made to Pakistan," McCaul said in a statement.

"This Pakistan connection just raises more red flags about this case and demonstrates why it's important for Congress to exercise its oversight authority," McCaul said.

The disparity between income of Hasan, who went on a shooting spree at the biggest US army base of Fort Hood, and his lifestyle has led to questions about how he spent money.
