An explosion ripped through a fertilizer plant Wednesday night in West, Texas, a witness told CNN.
A hospital in Waco, Texas, has been told to anticipate 100 injured people coming in from a fertilizer plant where there was a massive explosion, an official at the medical facility says. Glenn Robinson, CEO of Hillcrest Hospital, said a field triage station was set up at the plant some 18 miles north of Waco after the Wednesday night explosion.
Tommy Alford, who works in a convenience store about three miles from the plant, told CNN that several volunteer firefighters were at the store when they spotted smoke. Alford said the firefighters headed toward the scene and then between five and 10 minutes later, he heard a massive explosion.
CNN affiliate KWTX showed a photo of the explosion - which reportedly happened around 7:50 p.m. (8:50 p.m. ET) - showed a huge plume of smoke rising high into the air.FULL STORY
[Updated, 10:30 p.m. ET] Two men seen in images near the finish line of Monday's Boston Marathon - moments before two bombs there exploded - are of "high interest" and are considered "possible suspects," a law enforcement official said.
A circular sent out Wednesday by authorities indicated the attached photos, showing the two men, were being sent around "in an attempt to identify the individuals."The official said the men were of interest because of where they were at a particular time and what they were carrying. One of the men is seen carrying a black backpack.
The source said that authorities had not yet identified the two men by name and that the photographs were not being released to the public for fear of impeding the investigation.
Updated at 9:27 p.m. ET] As of Wednesday night, Boston-area hospitals had released 112 of the 178 treated for injuries sustained in the marathon attack. Thirteen patients are in critical condition, the same number as was reported earlier in the day.
[Updated at 7:32 p.m. ET]¬†The FBI has cancelled its Wednesday news briefing, the Boston police announced. Minutes earlier, police had said the federal agency would make a "brief statement" on the marathon case.
An arrest has been made in connection with possibly contaminated letters sent to President Obama and Sen. Roger Wicker, the Department of Justice said Wednesday.
Paul Kevin Curtis was arrested by the FBI at his home in Corinth, Mississippi, the department said in a statement.
Discovered Tuesday, the letters were addressed to Wicker, a Mississippi Republican, and to Obama. The justice department release said a third letter was sent to a Mississippi justice official.
The letters to Wicker and Obama were stopped at a government mail-screening facility after initial tests indicated the presence of the deadly poison ricin.
Because initial tests can be "inconsistent," the envelopes have been sent off for additional tests, an FBI statement said. The FBI does not expect to receive results from the tests until Thursday, federal law enforcement sources told CNN.
The letters read: "To see a wrong and not expose it, is to become a silent partner to its continuance."
They were signed "I am KC and I approve this message," a source said.FULL STORY

One of the two bombs used in the Boston Marathon attacks used a pressure cooker, the FBI said in a Joint Intelligence Bulletin.
The second device, the agency said, was housed in a metal container, "but currently there is insufficient evidence to determine if it was also a pressure cooker," the bulletin said.
The alert also said the fuzing system and method of initiation for the two devices are unknown.
The two devices, which exploded near the finish line of the Boston Marathon on Monday, left three people dead and more than 180 injured. No suspects have been identified.
