The surviving Boston Bombings suspect has been charged with conspiring to use a weapon of mass destruction.

If found guilty, the 19 year old faces the death penalty.

It's a week after two bombs rocked Boston - this evening the city fell silent to remember the victims.

Earlier today Emergency services formed a guard of honour at the first funeral for a victim of the Boston Marathon bombings.

29-year-old Krystle Campbell was among 3 killed last Monday.

People in the city also held a moment's silence this evening - exactly a week after the two explosions - to remember those who died.

Dzhokhar Tsarnaev (PRON: Tsar-nye-ev) remains in hospital - but American news networks are reporting he has started responding to questions in writing.

Meanwhile, officers also want to speak to his brother's wife, Katherine, as they try to work out a motive for the attacks.
