Boston marathon bombing suspect Dzhoskhar tsarnaev has pleaded not guilty to 30 charges including the use of a weapon of mass destruction.
His arm in a cast, tsarneav made his first courtroom appearance since his capture at the end of a chaotic week in april.
Wearing a bright orange overall he walked calmly into court 10 at the federal court in boston.
He fidgeted his seat and was then told to stand as the different charges were read to him.
The 19-years old smiled crookedly-he appeared to have a jaw injury-at his sisters.
Tsarneav leaned over a microphone and said, “not gulty” over and over in a russian accent,before being led out of the courtroom.
He made a kissing motion toward his family as he left.
