The father of the two Boston bombing suspects said Sunday that he has postponed a trip from Russia to the United States because of poor health. ‘‘I am really sick,’’ Anzor Tsarnaev, 46, told The Associated Press. He said his blood pressure had spiked to dangerous levels. Tsarnaev said at a news conference Thursday that he planned to leave that day or the next for the U.S. with the hope of seeing his younger son, who is under arrest, and burying his elder son, who was killed. His family, however, indicated later Thursday that the trip could be pushed back because he was not feeling well. During the past week, they were both questioned extensively by U.S. investigators who had traveled to Makhachkala from Moscow. They also were besieged by journalists who staked out their home. Tsarnaev’s family said last week that he intended to get to the U.S. by flying from Grozny, the Chechen capital, to Moscow. He and Tsarnaeva left Dagestan on Friday, but their whereabouts were unclear
The elder suspect in the Boston bombings regularly attended a mosque and spent time learning to read the Quran, but he struggled to fit in during a trip to his ancestral homeland in southern Russia last year, his aunt said. Tamerlan Tsarnaev seemed more American than Chechen and ‘‘did not fit into the Muslim life’’ in Russia’s Caucasus, Patimat Suleimanova told The Associated Press. She said when Tsarnaev arrived in January 2012, he wore a winter hat with a little pompom, something no local man would wear, and ‘‘we made him take it off.’’ After returning from Russia, Tsarnaev made his presence known at a Boston-area mosque, where his outbursts interrupted two sermons that encouraged Muslims to celebrate American institutions such as the July 4 Independence Day and figures like Martin Luther King Jr., according to the Islamic Society of Boston Cultural Center. During one incident congregants shouted at him, telling him to leave, the center said in a statement released Monday. His mother, Zubeidat Tsarnaeva, told the AP that her son greatly enjoyed his time with her relatives, but never traveled to her native village in a mountainous region of Dagestan, which is a hotbed of an ultraconservative strain of Islam known as Wahabbism. Wahabbism was introduced to the Caucasus in the 1990s by preachers and teachers from Saudi Arabia. The mother said her relatives now all live in Makhachkala and the town of Kaspiisk. She refused to say which mosque her son frequented, but Tsarnaev’s parents and aunt firmly denied that he met with militants or fell under the sway of religious extremists.
