The father of the two Boston bombing suspects says he is postponing a trip to the United States because of poor health.
Anzor Tsarnaev told The Associated Press on Sunday that he is "really sick" and his blood pressure had spiked.
Tsarnaev 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.
Tsarnaev confirmed that he is staying in Chechnya, a province in southern Russia, but did not specify whether he was hospitalized.
Until Friday, he and the suspects' mother had been living in the neighboring province of Dagestan.
