Mother says Boston suspects attended race last year

The mother of the two brothers suspected of the Boston Marathon bombing has told ITV News that her sons went to the event last year.

Her chilling admission comes a day after her youngest son was charged with the crime in hospital.

The mother of Tamerlan and Dzhokhar Tsarnaev remains adamant they are innocent. She has told ITV News that her children had 'nothing to do' with the explosions which killed three people.

Her surviving son though has been charged. From the family's home town in the Russian republic of Dagestan, ITV News Correspondent Martin Geissler spoke to Zubeidat Tsarnaev:

Reddit sorry for fuelling Boston bombings 'witch hunt'

The US website Reddit has apologised to the family of a student, Sunil Tripathi, who was incorrectly identified as a Boston bombing suspect by some of its readers.

A thread on the website entitled "findthebostonbombers" became a chat room for readers speculating on the identities of people seen in photographs of the aftermath of the bombings.

In a statement, Reddit said that many of its readers had used the website to help the investigation, by organising pizza deliveries to local hospitals and donating to relief funds, but that it had also helped to fuel a "witch hunt":

Though started with noble intentions, some of the activity on reddit fuelled online witch hunts and dangerous speculation which spiralled into very negative consequences for innocent parties ...

We have apologised privately to the family of missing college student Sunil Tripathi, as have various users and moderators.

We want to take this opportunity to apologize publicly for the pain they have had to endure.

The police officer who put the handcuffs on Boston bombing suspect Dzhokhar Tsarnaev after a large-scale manhunt in a suburb of the city has said it was a "good feeling".

"At a time like that, training kicks in," Saro Thompson of Boston Transit Police said. "We don't have emotion going into something like that."

Watch the full interview on the NBC News website.


Criminal complaint describes Boston suspect's reaction

The criminal complaint against Dzhokhar Tsarnaev - the 19-year-old man who has been charged over the Boston Marathon bombings - outlines how he can be seen in CCTV footage using his mobile phone just seconds before the first blast, and how his reaction sets him apart from the crowd:

A few seconds after he finishes the call, the large crowd of people around him can be seen reacting to the first explosion. Virtually every head turns to the cast (towards the finish line) and stares in that direction in apparent bewilderment and alarm. Bomber Two [Dzhokhar Tsarnaev], virtually alone among the individuals in front of the restaurant, appears calm.

Radical brand of Islam 'may have motivated suspects'

The two brothers suspected of bombing the Boston Marathon appear to have been motivated by a radical brand of Islam but do not seem connected to any Muslim terrorist groups.

The comments from US officials came after interrogating and charging Dzhokhar Tsarnaev with crimes that could bring the death penalty.

Speaking to NBC News, he said Dzohkhar was an innocent child - and described Tamerlan as a gifted boxer, but gentle - and homesick. But if Tamerlan had become alienated in America - angry or radicalized - his father says he didn't see it.

Anzor did not discuss Tamerlan's religious beliefs. He insists his sons are innocent, adding: "I need facts, proof. They have destroyed the reputation of all of us."
