Boeing says it will begin delivering 787s again in early May.

The 787 has been grounded since mid-January because of smoldering batteries. Federal authorities have approved Boeing's redesigned battery system.

South Carolina Gov. Nikki Haley has signed legislation to give the Boeing Co. $120 million in incentives for its expansion plans in the state.

Haley's spokesman Rob Godfrey told The Associated Press that the Republican governor signed the bill into law Tuesday afternoon.

In the years before the Boston Marathon bombings, Tamerlan Tsarnaev fell under the influence of a new friend, a Muslim convert who steered the religiously apathetic young man toward a strict strain of Islam, family members said.

Under the tutelage of a friend known to the Tsarnaev family only as Misha, Tamerlan gave up boxing and stopped studying music, his family said. He began opposing the wars in Afghanistan and Iraq. He turned to websites and literature claiming that the CIA was behind the terrorist attacks of Sept. 11, 2001, and Jews controlled the world.

Hackers have compromised the main Twitter account of The Associated Press, sending out an erroneous tweet about an attack at the White House.

The tweet, which said that there had been two explosions at the White House and President Barack Obama was injured, came after hackers made repeated attempts to steal the passwords of AP journalists.

Boston Marathon bombing suspect Tamerlan Tsarnaev was an ardent reader of jihadist websites and extremist propaganda, U.S. officials said Tuesday, adding another piece to the body of evidence they say suggests the two brothers were motivated by an anti-American, radical version of Islam.

As he lay in his hospital bed with a gunshot wound to the throat, Dzhokhar Tsarnaev, 19, was charged on Monday with carrying out the bombing with his older brother, who died last week in a gunbattle. Tsarnaev could get the death penalty.

Federal officials say they're delaying a policy that would allow passengers to carry small knives, bats and other sports equipment onto airliners.

The Transportation Security Administration said Monday that the policy change has been delayed to accommodate feedback from an advisory committee made up of aviation industry, consumer and law enforcement officials.

Police in Canada say two men have been arrested and charged with plotting a terrorist attack against a Canadian passenger train.

The Royal Canadian Mounted Police said Monday that Chiheb Esseghaier and Raed Jaser were conspiring to carry out an al-Qaida supported attack against Via Rail, but posed no imminent threat.

The investigation was part of a cross-border operation involving Canadian law enforcement agencies, the FBI and the U.S. Department of Homeland Security.

The two brothers suspected of bombing the Boston Marathon appear to have been motivated by a radical brand of Islam but do not seem connected to any Muslim terrorist groups, U.S. officials said Monday after interrogating and charging Dzhokhar Tsarnaev with crimes that could bring the death penalty.

Tsarnaev, 19, was charged in his hospital room, where he was in serious condition with a gunshot wound to the throat and other injuries suffered during his attempted getaway. His older brother, Tamerlan, 26, died Friday after a fierce gunbattle with police.

Surveillance video from the Boston Marathon attack shows one suspect dropping his backpack and calmly walking away from it before the bomb inside exploded, Massachusetts Gov. Deval Patrick said Sunday.

The video clearly puts 19-year-old Dzhokhar Tsarnaev at the scene of the attack, Patrick said on NBC's "Meet the Press."

 The family of an 8-year-old boy killed in the Boston Marathon bombing is offering its thanks to the investigators who worked around the clock on the case and the civilians who offered tips and images that helped authorities zero in on two suspects.

Martin Richard's family says it trusts that the justice system will now "do its job" after the arrest of 19-year-old suspect Dzhokhar Tsarnaev Friday night in the Boston suburb of Watertown. His brother and fellow suspect died in a shootout with police.

A 19-year-old college student wanted in the Boston Marathon bombings was taken into custody Friday evening after a manhunt that left the city virtually paralyzed and his older brother and accomplice dead.

Police announced via Twitter that Dzhokhar Tsarnaev was in custody. They later wrote, "CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won. Suspect in custody."

A law enforcement official says the suspect being hunted in the Boston Marathon bombing is in a boat stored in a Watertown, Mass., neighborhood.

The official said he was briefed on the situation and spoke on condition of anonymity because he's not authorized to discuss it publicly.

The official does not know if Dzhokhar Tsarnaev is dead or alive.

The Maloof family is asking NBA owners to approve the sale of the Kings to a Seattle group, saying there is "significant distance between us and the Sacramento group."

In a letter sent to the NBA's relocation and finance committee, and obtained by The Associated Press on Friday, the Maloof family said the Sacramento group originally matched the $525 million valuation for the franchise that Chris Hansen negotiated. Hansen then increased the valuation offer to $550 million last week.

The Federal Aviation Administration has accepted Boeing's revamped battery system for its beleaguered 787 Dreamliners and agreed to lift its grounding order, according to a congressional official.

The order gives Boeing the go ahead to begin retrofitting planes with an enhanced lithium ion battery system although the root cause of battery failures that caused a fire on one of the planes and smoke on another is still unknown.

Tamerlan Tsarnaev practiced martial arts and boxing, even aspiring to fight on the U.S. Olympic team. Dzhozkar Tsarnaev had been on the wrestling team at a prestigious high school and won a scholarship from the city to pursue higher education. Neighbors recalled the ethnic Chechen brothers, living on a quiet street in Cambridge, Mass., riding bikes and skateboards.

Two brothers, one dead, one alive and at large. After hours of only grainy images of two men in baseball caps to go on, a portrait gradually emerged Friday of the men suspected in the Boston Marathon bombing.

The brothers, who came from a Russian region near Chechnya, lived together on Norfolk Street in Cambridge. They had been in the country for about a decade, according to an uncle, Ruslan Tsarni of Montgomery Village, Md.
