Boston Bombings: Emotional Silent Tribute

Boston has held a minute's silence to remember the victims of the marathon bombings, after hundreds of people packed a church for the funeral of Krystle Campbell.

Later in the day, a memorial service was held at Boston University for another victim, Lu Lingzi, a graduate student from China.

Ms Campbell, 29, died with Ms Lu, 23, and Martin Richard, eight, last Monday when the devices exploded near the finish line of the race in the heart of the city.

People across the city had been asked to take part in the silent tribute at 7.50pm local time - exactly a week after the first of the deadly blasts went off.

At one spot near the scene of the attacks, hundreds lowered their heads and many prayed.

Hundreds of Ms Campbell's friends and family paid their respects earlier at St Joseph's Church, in her home town of Medford, north of Boston.

Dozens had to be turned away from the church and stood outside because the venue was full.

One mourner, Marishi Charles, said Ms Campbell's parents were too distraught to talk, so pastor Chip Hines spoke for them during the service, saying: "Krystle was always there for people."

At a wake on Sunday, well-wishers waited in a line lasting up to an hour to view photographs from throughout the young restaurant manager's life.

In the confused aftermath of the attacks, Ms Campbell's parents had been mistakenly told that their daughter - who had gone to watch a friend finish the race - was one of those being treated by medics. They later learned she was in fact among the dead.

Her mother, Patty, paid an emotional tribute last week, saying: "She was a wonderful person and everyone who knew her loved her.

"She was always smiling and was such a hard-worker in everything she did. This just doesn't make any sense."

Later in the day, Ms Lu's memorial service was held at Boston University where she was described as a sweet-hearted woman who was passionate about piano, her studies and loving life.

Hundreds of people including Massachusetts Governor Deval Patrick attended the service hosted by the university on Monday.

Ms Lu, from Shenyang in northeast China, studied statistics at the university. Friends and faculty say she was an exceptional student with a bubbly personality.

Boston University has launched a scholarship fund in Ms Lu's name.

More than 180 others were hurt in the attacks, at least 14 of whom lost all or part of a limb. Doctors have said all of those injured now appear likely to survive.

There are 51 people in hospital, with three in a critical condition - including a police officer who nearly bled to death in a shoot-out with the suspects.

Sky's Mike McCarthy, close to the scene of the blasts in Boston, reports messages of support and floral tributes have been left by visitors from all over the world.

Law enforcement officials say two brothers, Tamerlan and Dzhokhar Tsarnaev - ethnic Chechens from Russia - planted the devices among spectators at the race before they were tracked down later in the week.

After Tamerlan, 26, was killed in the gunfight in the early hours of Friday, 19-year-old Dzhokhar escaped, triggering a manhunt that brought Boston grinding to a halt.

It ended with the teenager's capture in a boat parked next to a house. He had suffered a gunshot wound to the neck.

The motive for the bombings remains unclear but Tsarnaev, who is unable to talk because of the throat injury, has been able to write responses to questions from his hospital bed and has now been charged over the attacks.
