Authorities in Yemen said suspects that were jailed for allegedly killing three American Christian missionaries and Yemeni politician were just part of planned attacks.
The murder suspects, Ali al-Jarallah and Abed Abdul Razak Kamel, gave police a list of eight targets during interrogation.
Yemeni officials have not released this information. At least 30 people have been detained in connection with Monday's killings.
Officials said they believe Kamel, the suspect in the missionary hospital killings, is linked to Osama bin Laden's al-Qaida terror network.
