A sister of the Boston Marathon bombing suspects was arrested Wednesday in New York on suspicion of making a bomb threat, police said.

Ailina Tsarnaeva, 24 and a resident of North Bergen, New Jersey, "was arrested and charged with aggravated harassment," a NYPD spokesman told Agence France Presse.

Prosecutors pushed back against a request by accused Boston Marathon bomber Djokhar Tsarnaev to change the venue of his trial, rejecting his attorneys' assertions that he cannot get a fair trial here.

In a 25-page court filing, prosecutors late Monday dismissed a defense petition seeking to relocate the trial from Boston to Washington.

A U.S. jury on Monday returned the first conviction over the 2013 Boston Marathon attacks, finding a friend of the prime suspect guilty of obstructing the investigation into the bombings.

Azamat Tazhayakov, 20, was convicted of obstruction and conspiracy over taking a backpack from alleged bomber Dzhokhar Tsarnaev's college dorm room in the days after the attacks.

A co-owner of The Philadelphia Inquirer and six other people were killed when a private business jet crashed during takeoff from an airfield outside Boston.

The Gulfstream IV jet burst into a fireball upon crashing late Saturday at LG Hanscom Field, located just northwest of Boston, killing all aboard.

One year after the deadly Boston Marathon bombings, the northeastern U.S. city on Tuesday will pay solemn tribute to the victims of the grisly attack that stunned the nation.

The solemn ceremonies will take place at the scene of the carnage at one of the world's nation's sporting events -- in the heart of the city, on Boylston Street.

Russia declined to provide the FBI with information about one of the Boston marathon bombing suspects two years before the attack, The New York Times reported Wednesday.

Three people were killed and about 260 wounded on April 15 last year when two bombs made of explosives-packed pressure cookers went off near the finish line of the marathon.

A U.S. judge on Wednesday set a November trial date for Dzhokhar Tsarnaev, the chief suspect accused of bombing last year's Boston marathon, killing three people and wounding 260 others.

The trial, which is likely to attract global media interest, will begin on November 3, federal judge George O'Toole ruled on Wednesday, said a spokeswoman for the prosecution.

The United States is to seek the death penalty for accused Boston bomber Dzhokhar Tsarnaev if he is convicted of involvement in the deadly attack, Attorney General Eric Holder said Thursday.

"The nature of the conduct at issue and the resultant harm compel this decision," Holder said in a statement on the prosecution of the 20-year-old, a U.S. citizen from a Chechen Muslim family.

A bomb scare on Monday forced Harvard University to evacuate four buildings, call in police and cancel final exams underway at the elite U.S. university in the northeastern town of Cambridge.

An alert on its website announced the evacuations at the Science Center, the Thayer dormitory, the Sever classroom and lecture hall and the Emerson building, home to the philosophy department.

Three friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev will be arraigned on Friday on charges of lying to investigators and conspiring to obstruct justice.

Dias Kadyrbayev and Azamat Tazhayakov, both 19-year-olds from Kazakhstan, had previously pleaded not guilty to charges of impeding the investigation into the April 15 attack that left three dead and scores injured.
