See this is the kind of stuff that I am talking about, we don't have to take this kind of garbage, now supposed some people died in this country behind these idiots, and I guess you all would still be saying, we should not do anything.
(CNN) -- Suspicious packages found in at least two locations abroad that were bound for the United States "apparently contain explosive material," President Barack Obama said Friday, calling the discovery "a credible threat against our country."
The packages led to increased searches of cargo planes and trucks in several U.S. cities, said law enforcement sources with detailed knowledge of the investigation.
U.S. officials believe that al Qaeda in the Arabian Peninsula, commonly referred to as AQAP, is behind the incident.
Obama confirmed that the packages originated in Yemen -- the stronghold of al Qaeda in the Arabian Peninsula.
The suspicious package from Yemen had wires and a circuit board, a law enforcement source said.
"We also know that al Qaeda in the Arabian Peninsula ... continues to plan attacks against our homeland, our citizens, and our friends and allies," he said during a press briefing on the incident.
One suspicious package, found in the United Kingdom, contained a "manipulated" toner cartridge and had white powder on it as well as wires and a circuit board, a law enforcement source said. A similar package was discovered in Dubai, in the United Arab Emirates, the source said. The UAE General Authority of Civil Aviation issued a statement saying the package was to be shipped on a FedEx cargo plane.
Both packages were bound for the United States, "specifically two places of Jewish worship in Chicago," Obama said.
"Initial examination of those packages has determined they do apparently contain explosive material," he said.
White House counterterrorism chief John Brennan, who was the first to brief Obama on the potential threat Thursday night, said that "the materials that were found and the device that was discovered were intended to do harm."
Brennan, while declining to provide specifics, also said intelligence officials were specifically looking for such suspicious packages when the first discovery -- the package in the United Kingdom -- was made.
After the packages were found Thursday night and Friday morning, authorities were tracking about 13 other packages shipped from Yemen, a law enforcement source said. Some of them had been found and an investigation of those had not indicated they are a threat, the source said.
