** FBI Suspects Boston Bombs Packed in Pressure Cookers**
The FBI says the two bombs that exploded Monday at the Boston Marathon were carried in a dark-colored bag, and possibly consisted of pressure cookers packed with nails and ball bearings.
FBI examiners are looking at fragments recovered from the scene, as they try to piece together how the attack happened.
Authorities do not have any suspects, and are asking the public to send in any photos or videos taken along the marathon route to help find who was responsible.
VOA correspondent Carolyn Presutti, reporting in Boston, says police are also asking people to call in any possible tips.
Police and firefighters unions in Boston have offered a $50,000 reward for information leading to an arrest.
The FBI agent in charge of the case says investigators will "go to the ends of the Earth" to identify who carried out the bombings.
Maryland Congressman Dutch Ruppersberger said after a security briefing Tuesday it is not likely that al-Qaida or any foreign government was involved because of the lack of prior intelligence.
Two blasts seconds apart killed three people at the finish line of the Boston Marathon, including an 8-year-old boy. One-hundred-76 people were injured. A number of them lost limbs.
**Britain, World Dignitaries Say Goodbye to 'Iron Lady'**
World leaders and dignitaries from 170 countries will attend the funeral of former British Prime Minister Margaret Thatcher amid heavy security at St. Paul's Cathedral in London Wednesday.
Britain's Queen Elizabeth, her husband Prince Phillip, and Prime Minister David Cameron will lead the more than 2,000 guests expected to attend the service. Former U.S. Secretary of State Henry Kissinger and ex-Vice President Dick Cheney will also attend.
Mrs. Thatcher's body was brought Tuesday to Westminster Palace, to rest overnight before the funeral. Her coffin will be carried in a funeral procession Wednesday morning along a central London route lined by members of the British armed forces.
More than 4,000 police also will be deployed as part of a security operation that was increased following Monday's deadly bomb attacks in Boston. Officials say they are well-prepared to deal with the security for the funeral, as well as the London Marathon on Sunday.
Mrs. Thatcher died from a stroke April 8 at the age of 87. Britain's first and only female prime minister, she became one of the country's most influential modern-day leaders during her time in office from 1979 to 1990.
