MAKHACHKALA, Russia — Russian agents placed the elder Boston bombing suspect under surveillance during a six-month visit to southern Russia last year, then scrambled to find him when he suddenly disappeared after police killed a Canadian jihadist, a security official told The Associated Press.
U.S. law enforcement officials have been trying to determine whether Tamerlan Tsarnaev was indoctrinated or trained by militants during his visit to Dagestan, a Caspian Sea province that has become the center of a simmering Islamic insurgency.
The security official with the Anti-Extremism Center, a federal agency under Russia's Interior Ministry, confirmed the Russians shared their concerns. He told the AP that Russian agents were watching Tsarnaev, and that they searched for him when he disappeared two days after the July 2012 death of the Canadian man, who had joined the Islamic insurgency in the region. The official spoke only on condition of anonymity because he was not authorized to speak to the news media.
Security officials suspected ties between Tsarnaev and the Canadian — an ethnic Russian named William Plotnikov — according to the Novaya Gazeta newspaper, which is known for its independence and investigative reporting and cited an unnamed official with the Anti-Extremism Center, which tracks militants. The newspaper said the men had social networking ties that brought Tsarnaev to the attention of Russian security services for the first time in late 2010.
It certainly wouldn't be surprising if the men had met. Both were amateur boxers of roughly the same age whose families had moved from Russia to North America when they were teenagers. In recent years, both had turned to Islam and expressed radical beliefs. And both had traveled to Dagestan, a republic of some 3 million people.
The AP could not independently confirm whether the two men had communicated on social networks or crossed paths either in Dagestan or in Toronto, where Plotnikov had lived with his parents and where Tsarnaev had an aunt.
After Plotnikov was killed, Tsarnaev left suddenly for the U.S., not waiting to pick up his new Russian passport — ostensibly one of his main reasons for coming to Russia. The official said his sudden departure was considered suspicious.
Plotnikov's father told the Canadian network CBCNews on Monday that his son had broken off contact when he returned to Russia in 2010 and he had no way of knowing whether his son knew Tsarnaev.
In an August interview with the Canadian newspaper National Post, Vitaly Plotnikov said his son, who was 23 when he died, had converted to Islam in 2009 and quickly became radicalized. But he said he fully understood what his son was up to in Russia only when he received photographs and videos after his death.
In one photo, a smiling William Plotnikov is shown posing in the woods, an automatic rifle slung over his shoulder and a camouflage ammunition belt around his waist. In the videos, which the National Post reporter watched with the father, the younger Plotnikov talked openly of planning to kill in the name of Allah.
Plotnikov had been detained in Dagestan in December 2010 on suspicion of having ties to the militants and during his interrogation was forced to hand over a list of social networking friends from the United States and Canada who like him had once lived in Russia, Novaya Gazeta reported.
The newspaper said Tsarnaev's name was on that list, bringing him for the first time to the attention of Russia's secret services.
Novaya Gazeta, which is part-owned by former Soviet President Mikhail Gorbachev and wealthy businessman Alexander Lebedev, has regularly criticized the Kremlin. One of its best known reporters, Anna Politkovskaya, angered the Kremlin with her reporting from Chechnya, and her 2006 murder in a Moscow elevator was widely presumed to have been in connection with her journalistic work.
The Islamic insurgency in Dagestan grew out of the fierce fighting between Russian troops and separatists in neighboring Chechnya that raged in the 1990s. Attacks now are carried out almost daily in Dagestan against police and security forces, who respond with special operations of their own to wipe out the militants.
As recently as Sunday, two suspected militants were killed in a shootout after being cornered in a house in the Dagestani village of Chontaul, according to police spokeswoman Fatina Ubaidatova.
Plotnikov was among seven suspected militants killed on July 14 during a standoff with police in the Dagestani village of Utamysh, according to the official police record.
After Plotnikov's death, Russian security agents lost track of Tsarnaev and went to see his father in Makhachkala, the capital of Dagestan, who told them that his son had returned to the U.S., Novaya Gazeta said.
The agents did not believe the father, since Tsarnaev had left without picking up his new Russian passport, and they continued to search for him, the newspaper reported.
The Russians later determined that Tsarnaev had flown to Moscow on July 16 and to the United States the following day, the newspaper said. Tsarnaev arrived in New York on July 17.
Russian migration officials have said they were puzzled that Tsarnaev applied for the passport but left before it was ready.
His father, Anzhor Tsarnaev, said last week that his elder son stayed with him while waiting for the passport to be processed. He could not be reached Tuesday for comment on the Novaya Gazeta report.
The Tsarnaev family had lived briefly in Dagestan before moving to the United States a decade ago. Both parents returned to Dagestan last year.
The official with Russia's Anti-Extremism Center said Tsarnaev was filmed attending a mosque in Makhachkala whose worshippers adhere to a more radical strain of Islam. The official would give no further details about what the Russian security services knew about Tsarnaev's activities in Dagestan or about any possible connection to Plotnikov.
The AP was unable to determine whether the official was the same one who provided the information to Novaya Gazeta.
Plotnikov had settled in Utamysh, a small village about 70 kilometers (40 miles) from Makhachkala. It was not known whether he had spent any significant amount of time in Dagestan's capital.
Novaya Gazeta said Tsarnaev was also seen in the company of Mahmud Nidal — a man who was both Palestinian and Kumyk, one of the dozens of ethnic groups living in Dagestan — and who was believed to have ties to Islamic militants in the southern Russian region.
Nidal was killed in May 2012 after refusing to give himself up to security forces that had surrounded a house in Makhachkala, according to official police records.
Shortly after Plotnikov identified Tsarnaev during his December 2010 interrogation, the Russian secret services, the FSB, studied Tsarnaev's pages on social networking sites and asked the FBI for more information, the Russian newspaper said.
The FBI has acknowledged receiving the request. The U.S. agency said it opened an investigation, but when no evidence of terrorism was found and no further information from the Russians was forthcoming, the case was closed in June 2011.
