"I heard this bang and I thought it was a bird scarer," Reuters photographer Peter Nicholls recalls, describing the moment a man fire-bombed the gates of a centre for processing migrants in the English port of Dover and then took his own life.
It was a dreary day in the south coast town and Nicholls was taking pictures to illustrate a story on tension between Britain and France over who should handle thousands of migrants who make the dangerous trip over the English Channel each year.
