Two Muslim militants accused of killing three American Christian missionaries and a Yemeni politician had also planned attacks on journalists and other foreigners, security officials said today.
The Yemeni officials said investigators have compiled a list of eight targets after interrogating the suspects, both described as fundamentalist Muslims.
Mr Ali al-Jarallah is accused of shooting and killing Mr Jarallah Omar, deputy leader of Yemen's Socialist Party, last week and Mr Abed Abdul Razak Kamel is accused of shooting and killing three Americans and wounding a fourth in an attack on a missionary hospital in southern Yemen on Monday.
The officials did not give the full list nor name the foreigners, politicians and journalists on it. But they said the targets included a guest house used by Ismaili Muslims in San'a. Some fundamentalist Muslims believe Ismailism, which has roots in the beliefs of the ancient Persians, is heretical. Its head is the Aga Khan
The officials did not say whether the suspects had described how they planned to carry out further attacks.
Investigators believe the two suspects are part of a larger terrorist cell in Yemen that is also plotting more attacks on foreigners.
Yemeni officials have said they have strong suspicions Kamel is linked to the al-Qaeda terror group led by Osama bin Laden. Yemen is bin Laden's ancestral homeland and has been a fertile recruiting ground for al-Qaeda.
