The surviving suspect in the Boston Marathon bombing has been named by police as Dzhokhar Tsarnaev.
The 19-year-old who was previously referred to as “suspect number two” or “the suspect in a white hat” is the younger brother of 26-year-old Tamerlan Tsarnaev, who was shot dead earlier by police.
The siblings lived in the Massachusetts town of Cambridge, and are thought to have been in the US since 2001.
Their country of origin is believed to be the southern Russian republic of Chechnya, which is predominantly Muslim.
According to his page on a Russian social networking site, Dzhokhar Tsarnaev is a graduate of Boston’s Cambridge Ridge & Latin School. He received a scholarship to pursue his studies and is a keen wrestler.
He is also a member of groups devoted to Chechnya and lists Islam as his world view.
Speaking to the media from Dagestan, Russia, his father said he was a second-year medical student in the US and described him as “a true angel”.
There have also been reports that the family lived in the Central Asian nation of Kyrgyzstan, and were refugees from Chechnya’s conflict with Russia in the early 1990s.
