Quote:Nashville explosion 'probably suicide bombing'BBC:
'The camper van blast in Nashville on Christmas Day was probably a suicide bombing, law enforcement officials
are quoted as saying by US media.
Investigators are conducting DNA tests after human remains were found near the site of the powerful blast.
The home of a possible person of interest was searched on Saturday in Nashville's suburb of Antioch.
The blast injured three people and disrupted communications systems in Tennessee and four other states.
No motive has yet been established for the explosion in the state of Tennessee, and no-one has yet said they were behind it.
Meanwhile, businesses and TV personalities have offered more than $300,000 (£224,000) to catch those responsible.
What are the latest developments?
Investigators now believe that the blast was likely the result of a suicide bombing, according to two law enforcement sources
cited by CNN. CNN is also quoting an FBI official as saying that agents are not looking for another suspect after the human
remains were found.
CBS News says the leading theory now is that the subject may have been killed in the blast.
Newsweek reports that the investigators are trying to find the suspect's mother to conduct DNA tests.
FBI Special Agent in Charge Douglas Korneski earlier said officials had received about 500 tips possibly relating to the explosion.
After visiting the site, Tennessee Governor Bill Lee said it was a "miracle" that no-one had been killed...'

Quote:Authorities probing Nashville blast converge on home in city’s suburbsMSN:
'Authorities investigating the Christmas morning explosion in downtown Nashville converged on a home in this neighborhood
about 10 miles southeast of the blast site Saturday afternoon, as law enforcement agents continued to gather evidence and
run down hundreds of tips.
Investigators think the person living at that address has a connection to the bombing. One theory investigators are pursuing is
that the man blew himself up in the RV, according to two people familiar with the matter, who cautioned that officials are still
pursuing numerous leads and that no final conclusions have been reached.
Several neighbors said a light-colored recreational vehicle similar to the one that blew up Friday morning had been parked in
the backyard of the home for several months before the explosion. So far, investigators have not found evidence pointing to
other potential conspirators or threats to public safety, according to multiple people familiar with the case.
A day after the explosion, AT&T communication networks remained disrupted throughout Tennessee, knocking out residential
phones, cellphones and service at 20 call centers for 911. Business and government functions were hobbled, and flights were
temporarily grounded at Nashville International Airport...'
