Anzor Tsarnaev, father of the Boston Marathon bombing suspects, says he is postponing a trip to the U.S. to visit his hospitalized son Dzhokhar and collect Tamerlan’s body due to his spiking blood pressure.

Anzor Tsarnaev, 47, told The Associated Press on Sunday that he is “really sick” and his blood pressure had spiked.

He said last week that he planned to travel from Russia to the U.S. with the hope of seeing his younger son, who is under arrest, and burying his elder son, who was killed in a clash with police.

The news comes days after it was revealed that the suspects’ mother, Zubeidat Tsarnaeva, was placed on a CIA watchlist 18 months before the Boston Marathon attack.

Anzor Tsarnaev confirmed that he is staying in Chechnya, a province in southern Russia, but did not specify whether he had been hospitalized.

Until Friday, Anzor Tsarnaev and the suspects’ mother had been living in the neighboring province of Dagestan.

Zubeidat Tsarnaeva claimed she had to call an ambulance for her husband on Thursday but did not elaborate on what happened.

It was revealed last week that both parents have left their home in Dagestan for another part of Russia.

Zubeidat Tsarnaeva was never planning to accompany her husband to the U.S. because she faces felony shoplifting charges here.

On April 25, the parents held a bizarre press conference in which they claimed that the gruesome carnage of the Boston attacks, which killed three people and injured more than 280, were staged by the U.S. government.

“America took my kids away from me,” Zubeidat Tsarnaeva cried.

“I’m sure my kids were not involved in anything.”

She went so far as to claim that the blood covering the streets after the blasts was in fact paint.

Tamerlan Tsarnaev, 26, was killed in a police shootout on April 19 and 19-year-old Dzhokhar was taken into custody – alive, but badly injured – less than 24 hours later in Watertown, Massachusetts following a massive manhunt.

After spending nearly a week in a Boston hospital recovering from gunshot wounds sustained during a firefight with police, Dzhokhar Tsarnaev was transferred to the Federal Medical Center Devens on April 26.

Dzhokhar Tsarnaev has been charged in the Boston Marathon attacks and is facing a maximum sentence of the death penalty or life in prison.

The Tsarnaev family emigrated to the U.S. a decade ago, but both parents returned to Russia last year.

Anzor Tsarnaev said Thursday that he was planning to travel to the U.S. as soon as Friday, but hadn’t yet bought a plane ticket.

Banging the table in front of him, Anzor Tsarnaev said: “I am going to the United States. I want to say that I am going there to see my son, to bury the older one.

“I don’t have any bad intentions. I don’t plan to blow up anything. I am not angry at anyone. I want to go find out the truth.”

Zubeidat Tsarnaeva, 45, also described a figure known only as “Misha” – who has been pinpointed as a source of radicalization for her son Tamerlan Tsarnaev.

The mother said that he was a “very nice man”, of Armenian origin and living in Boston. “Misha” is also apparently a convert to the Islamic faith.

Anzor Tsarnaev has already been interviewed by Russian and American authorities – and would face further interviews if he ever gets to the U.S.
