Tamerlan and Dzhokhar Tsarnaev used al-Qaeda online magazine to make pressure cooker bombs

Tamerlan and Dzhokhar Tsarnaev apparently used an online magazine produced by al-Qaeda as their guide for how to make pressure cooker bombs that they set off at the finish line of last week’s Boston Marathon, killing three and injuring more than 180 others.

Dzhokhar Tsarnaev, 19, reportedly confessed to the FBI that he and his brother Tamerlan were the ones behind the bombing and that they acted alone.

The Boston bomber also said that they were driven to commit the attack because of their feelings against the wars in Iraq and Afghanistan.

Dzhokhar Tsarnaev remains in a Boston hospital but he is expected to be transported in the next few days as his condition was downgraded from “serious” to “fair”.

The suspect sustained unspecified damages during the course of the last week, most likely from the firefight with police on Friday morning that led to the death of his brother, Tamerlan Tsarnaev.

Dzhokhar Tsarnaev is reportedly telling investigators that the deadly attacks were spearheaded by his brother, Tamerlan, who is thought to be the more radical of the two.

Tamerlan Tsarnaev, a 26-year-old father of one, allegedly went through fits of rage, both verbally and physically abusing his wife who he called a “slut” and a “prostitute”.

Federal investigators have already questioned Tamerlan Tsarnaev’s wife, 24-year-old Katherine Russell Tsarnaev, and the brothers’ parents, Zubeidat Tsarnaeva and Anzor Tsarnaev, are thought to be on their way to America for questioning from their native Russia.

It was revealed earlier today that no relatives have claimed Tamerlan Tamerlan’s body.
