New York bombing suspect

New York bombing suspect warned Trump on Facebook

"Trump you failed to protect your nation," it read. The post by Akayed Ullah was revealed in charges filed by federal prosecutors on Tuesday.

They say the 27-year-old Bangladeshi immigrant carried out the bombing inspired by the Islamic State group.

He wounded himself and three others in Monday morning's attack.

Mr Ullah is accused of blowing up a crude device strapped to his body in an underpass at Manhattan's Port Authority Bus Terminal during the rush hour.
