Two U.S. officials say a notebook with extremist ramblings was found when the man suspected of placing bombs in New York City and New Jersey was taken into custody.

The Associated Press viewed a blood-stained page of the notebook. It contained a reference to Anwar al-Awlaki, a U.S.-born cleric killed in a 2011 drone strike, and Nidal Hasan, the former U.S. Army major who went on a 2009 rampage at the Fort Hood military installation.

The page includes the phrase “Join us in our New front.”

The officials also said that Ahmad Khan Rahami had traveled to Pakistan in recent years. One said he arrived from Afghanistan with his family as a young child.

The officials were not authorized to publicly reveal details of the investigation and spoke to the AP on condition of anonymity.
