People living in Boston have been united in grief as they try to come to terms with the two bomb attacks at the Boston Marathon that killed three people and injured many more.

Flowers and declarations of love and support have been piling up, just a few blocks from the bomb sites and US President Barack Obama is to attend an interfaith service to show solidarity and support for the city.
