[JURIST] A father and son were indicted [US DOJ press release, PDF] by a federal grand jury in California Thursday for allegedly lying to the FBI about the son attending a terrorist training camp in Pakistan with connections to al-Qaida. Umer Hayat and his son Hamid Hayat were arrested and charged [JURIST report] last Wednesday after the father admitted he paid for his son to attend the camp, which was run by a friend of the Hayat family. The FBI alleges that Hamid attended the camp for six months in 2003 and 2004 with plans to execute attacks on the US upon his return. The Hayats are challenging the government [JURIST report] because two different affidavits outlining the charges against them were released - one version to the court and another version to the media.
