Kenyan authorities have freed an American woman and her Spanish husband after finding no connection between them and the terrorist attacks against Israelis in Mombasa.
At least 10 others -- six Pakistanis and four Somalis -- are still being held for questioning in the case, but Kenyan authorities say they have found no links between those suspects and the al-Qaida terror network.
The American woman and her husband were detained for two days for interrogation about the attacks in Mombasa on Thursday -- a car bomb that wrecked an Israeli-owned resort hotel and a simultaneous unsuccessful attempt to shoot down an Israeli airliner. The bombing killed 15 people, including three attackers.
Authorities say police became suspicious of the American woman and her husband because they checked out of their room at another nearby hotel just after the devastating explosion at the Paradise Hotel resort. Authorities are trying to find the owner of the vehicle used by the suicide bombers. Its engine and registration numbers were found in the rubble of the hotel.
Israeli and U-S investigators are helping Kenyan authorities with the investigation. U-S officials say it is too early to be certain who carried out the attacks, but suspicion is growing that al-Ittihad al-Islamiya, a militant group based in Somalia that has ties to al-Qaida, may have been involved.
On Thursday, a previously unknown group calling itself the Army of Palestine contacted reporters in Lebanon to claim responsibility for the attacks.
In Israel, Prime Minister Ariel Sharon is vowing to hunt down those responsible for the suicide attack in Kenya. Mr. Sharon says the long arm of Israel's security forces will reach those who carried out the terror attacks.
