Bomb survivor pulled from rubble
A man was found alive after 36 hours in the wreckage
Dozens of FBI agents are working in and around the badly-damaged embassy building in Nairobi which was sealed off by armed American marines after the attack.
Foreign help has been arriving in Kenya, including an Israeli team with sniffer dogs which is searching in the rubble of the Co-operative Bank next to the embassy.
American investigators are expected later on Sunday in Tanzania, where at least nine people died in the attack on the American embassy.
Man found alive
Rescuers pulled a 45-year-old man alive from the wreckage of the bank building in Nairobi on Saturday evening - 36 hours after the bomb blasts.
Our correspondent says there was "a surge of joy and hope" among the rescuers when the man, who had been trapped between slabs of concrete, was pulled free.
The search teams said at least one other person was still alive in the rubble - a woman they had managed to speak to.
Earlier on Saturday, a man whose cries were heard in the wreckage of the building died after rescuers spent four hours clearing debris to find him.
More than 100 people are said still to be unaccounted for.
Security camera clue
The car park behind the Nairobi embassy, where a car bomb is believed to have exploded, was monitored by security cameras.
The US ambassador, Prudence Bushnell, who suffered minor injuries in the attack, said she did not know whether the recordings survived the blast.
An FBI official said the investigators' priority would be to determine the kind of vehicle and the type of explosive device used, which he said could be like a fingerprint of those responsible.
The former US ambassador to Kenya, Smith Hempstone, said: "I immediately thought of the usual suspects - Libya, Syria, Iran, Iraq, the PLO.
"I'd like to think (we'll) run them down and terminate them with extreme prejudice, as they used to say in Vietnam."
The US President, Bill Clinton, has again stressed Washington's determination to catch the bombers.
"No matter how long it takes or where it takes us we will pursue terrorists until the cases are solved and justice is done," he said in a radio address from the White House on Saturday.
There are also unconfirmed reports that one man was arrested in Nairobi in connection with the bombing.
