Christians destroy 'Piss Christ' work

French police are hunting two men who destroyed a US artist's photograph of a plastic crucifix submerged in his own urine.

The men, armed with a hammer and a screwdriver, attacked the work "Piss Christ" by Andres Serrano at an exhibition in Avignon on Sunday, AFP news agency reported.

The attack followed a protest by conservative Christians outside the gallery on Sunday. The work triggered uproar in 1987 when it won a prize from a group part-funded by the US taxpayer.
