World News :At least three dead, 144 injured as two bombs hit Boston Marathon finish line

The final runners of the Boston Marathon were trickling in Monday afternoon when twin bombs exploded near the finish line raising alarms that terrorists might have struck again in the U.S.

But as the FBI took charge of the investigation, authorities shed no light on a motive or who may have carried out the bombings, and police said they had no suspects in custody.
The Boston Marathon came to a halt after two explosions occurred near the race's finish line. Preliminary reports say at least three are dead and more than 140 injured. The FBI has now taken over the ongoing criminal investigation. The next briefing will be Tuesday at 9:30 a.m. EST.

BOSTON — Two bombs exploded in the crowded streets near the finish line of the Boston Marathon on Monday, killing at least three people and injuring more than 140 in a bloody scene of shattered glass and severed limbs that raised alarms that terrorists might have struck again in the United States.
A White House official speaking on condition of anonymity because the investigation was still unfolding said the attack was being treated as an act of terrorism.

WBZ-TV reported late Monday that law enforcement officers were searching an apartment in the Boston suburb of Revere. Massachusetts State Police confirmed that a search warrant related to the investigation into the explosions was served Monday night in Revere but provided no further details.

Some investigators were seen leaving the Revere house early Tuesday carrying brown paper bags, plastic trash bags and a duffel bag.

President Barack Obama, speaking from the White House late Monday, pointedly avoided using the words "terror" or "terrorism," saying officials "still do not know who did this or why." However, a White House official later said the explosions at one of the world's oldest and most prestigious races were being treated as terrorism.
"We will find out who did this. We'll find out why they did this," Obama said in his brief statement. "Any responsible individuals, any responsible groups, will feel the full weight of justice."
