Islamabad, Pakistan (CNN)  -- Five people arrested in Pakistan had been reported missing in the United States, and police are confident they were planning terrorist acts, a Pakistani police official told CNN.





It is too soon to link the men with any terrorist organizations, said Tahir Gujjrar, deputy superintendent of police in Sargodha, Pakistan, but preliminary investigations suggest they had sought to link up with the Jaish-e-Mohammed and Jamaat ud Dawa militant organizations. Neither group showed interest, however, Gujjrar said.





The five were from Virginia and their families had contacted the FBI soon after they went missing, he said. They include two Pakistani-Americans, two Yemeni-Americans and an Egyptian-American.





The arrests came after a raid on a home in Sargodha, about 120 miles south of Islamabad, Gujjrar said.





No U.S. officials have confirmed Gujjrar's information, and there was no evidence charges had been filed. The FBI had said earlier that it was trying to determine whether a link existed between the five missing men and the arrests in Pakistan.





A U.S. law enforcement official not authorized to speak for attribution said the five missing men were all American citizens. Asked if they are the same men arrested in Pakistan, the official said, "We think it is, but we don't have it firm ... The truthful answer is, we don't know."





The State Department said it does not have confirmation of the arrested individuals' identities or whether they are Americans. The U.S. embassy in Islamabad is seeking further information.





If the individuals are Americans, the United States will be seeking consular access, State Department spokesman Ian Kelly said.





"If they are American citizens, we are going to be very interested in the charges they have been detained on and the circumstances in which they are being held," he said. "That is something we would do anywhere and that is why the embassy is seeking further information."





Under the Geneva Conventions, Pakistan is required to notify the United States about any Americans arrested, Kelly said.





The U.S. law enforcement official said none of the five missing men had shown up on law enforcement's radar before they were reported missing. "These guys never surfaced with us before."





Authorities believe their intent was to wage jihad overseas rather than with terrorist acts in the United States, the official said, but "there is still a lot of uncertainty about what they were up to."





A Pakistani official said the men arrived in Karachi on November 30 and went on to Lahore and then Sargodha, where they were arrested Wednesday, the official said. The arrests came at the behest of local police. Preliminary investigations are ongoing, the official said.





The Council on American-Islamic Relations said in a statement Wednesday it was assisting in the investigation of "five Muslim young men from Virginia who left the country recently under mysterious circumstances."





The parents of the missing youths and local Muslim leaders approached the council about the disappearances and the organization "immediately informed the FBI," the council said.





Council spokesman Ibrahim Hooper said one of the missing youths was a student at Howard University, and all five knew each other.





One of the youths left a video behind, Nihad Awad, the council's executive director, told reporters. "I was disturbed by the content of it," he said.





One person appeared in it, and made references to "the ongoing conflict in the world, and that young Muslims have to do something," Awad said. He said the video "juxtaposed certain verses of the Quran," and he suggested there was a misunderstanding of those verses and their potential misuse.





The video is about 11 minutes long, he said, and is "like a farewell." Awad said it did not specify what the youths would be doing, but he has seen similar videos on the Internet, and "it just made me uncomfortable."





One source identified the missing Howard student as Ramy Zamzam, who was studying dentistry at the Washington college. No further details were immediately
