INFORMAL TRIBUTES to the victims of the Boston Marathon bombings across New York City, in a remarkable moment of solidarity between the two cities.

The cities are often great rivals on sports fields, particularly in the bitter baseball rivalry between the Yankees and the Red Sox – but many set aside the historical antagonism between the sides as Boston came to terms with the marathon bombings.

One such example was this display erected outside the Brooklyn Academy of Music:

Meanwhile, British rock band Muse - who played in Boston only two nights ago - set aside a moment at their performance in Madison Square Garden last night to play the US national anthem in a tribute to those who had been traumatised by the Boston bombings.

Video of the performance can be seen here.

And from the International Space Station, Canadian astronaut Chris Hadfield ensured that his trademark photographs of cities around the world were capped with an overhead photograph of Boston:
