Russian authorities secretly recorded a telephone conversation in 2011 in which one of the Boston bombing suspects vaguely discussed jihad with his mother, officials said Saturday, days after the US government finally received details about the call.
In another conversation, the mother of now-dead bombing suspect Tamerlan Tsarnaev was recorded talking to someone in southern Russia who is under FBI investigation in an unrelated case, officials said.

The conversations are significant because, had they been revealed earlier, they might have been enough evidence for the FBI to initiate a more thorough investigation of the Tsarnaev family.

As it was, Russian authorities told the FBI only that they had concerns that Tamerlan and his mother were religious extremists.
With no additional information, the FBI conducted a limited inquiry and closed the case in June 2011.
Two years later, authorities say Tamerlan and his brother, Dzhohkar, detonated two homemade bombs near the finish line of the Boston Marathon, killing three and injuring more than 260. Tamerlan was killed in a police shootout and Dzhohkar is under arrest.
In the past week, Russian authorities turned over to the United States information it had on 26-year-old Tamerlan and his mother, Zubeidat Tsarnaeva.
The Tsarnaevs are ethnic Chechens who emigrated from southern Russia to the Boston area over the past 11 years.
Even had the FBI received the information from the Russian wiretaps earlier, it's not clear that the government could have prevented the attack.
In early 2011, the Russian FSB internal security service intercepted a conversation between Tamerlan and his mother vaguely discussing jihad, according to US officials who spoke on condition of anonymity because they were not authorized to discuss the investigation with reporters.
The two discussed the possibility of Tamerlan going to 'Palestine,' but he told his mother he didn't speak the language there, according to the officials, who reviewed the information Russia shared with the US.
It was not immediately clear why Russian authorities didn't share more information at the time. It is not unusual for countries, including the US, to be cagey with foreign authorities about what intelligence is being collected.
Jim Treacy, the FBI's legal attache in Moscow between 2007 and 2009, said the Russians long asked for US assistance regarding Chechen activity in the United States that might be related to terrorism.
"On any given day, you can get some very good cooperation," Treacy said. "The next you might find yourself totally shut out."
Zubeidat Tsarnaeva has denied that she or her sons were involved in terrorism. She has said she believed her sons have been framed by US authorities.
But Ruslan Tsarni, an uncle of the Tsarnaev brothers and Zubeidat's former brother-in-law, said Saturday he believes the mother had a "big-time influence" as her older son increasingly embraced his Muslim faith and decided to quit boxing and school.
After receiving the narrow tip from Russia in March 2011, the FBI opened a preliminary investigation into Tamerlan and his mother. But the scope was extremely limited under the FBI's internal procedures.
After a few months, they found no evidence Tamerlan or his mother were involved in terrorism.
The FBI asked Russia for more information. After hearing nothing, it closed the case in June 2011.
In the fall of 2011, the FSB contacted the CIA with the same information. Again the FBI asked Russia for more details and never heard back.
At that time, however, the CIA asked that Tamerlan's and his mother's name be entered into a massive US terrorism database.
