Pilot crashes plane into tax agency office

The suicide attack left one person dead and 13 injured inside the Austin building. Stack,53,who crashed the Piper Dakota into the building,was also confirmed dead.

The incident was described as an intentional assault on a US government institution,but authorities have said the crash did not appear to have any terror links.

“This appears to be an intentional act by a sole individual and it appears this individual was targeting federal offices in that building,” Austin police chief Art Acevedo told reporters.

Fighter jets scrambled over the building following the incident that brought back shocking memories of the September 11,2001 terror attacks.

A US law official said investigators were looking at a lengthy,anti-government “manifesto,” Stack is believed to have written on his website. The message outlines problems with the IRS and says violence “is the only answer”.

The site is titled,”Well Mr Big Brother IRS man … take my pound of flesh and sleep well.”
