The family of the Fort Hood shooting suspect Nidal Hasan is rejecting claims he was linked to Islamist radicals, Sky News reported.

A close relative spoke to Sky News in the West Bank town of Ramallah on condition of anonymity, afraid of reprisals against his family in the U.S.

With Hasan now out of a coma in the hospital, his relative spoke of the extreme pressures the military doctor had been working under, treating injured patients returning from wars in Iraq and Afghanistan.

"He was taking things very personally. When he talked about certain patients he was crying," the relative said, according to Sky News.

"He was complaining there was not enough time to treat his patients properly. He could not separate his emotions from his job."

The relative insists the U.S. military had a duty of care to its employee which it may have neglected with tragic consequences, Sky News reported.
