Medical help has begun arriving in Nairobi where official figures confirm 132 people died and more than 2,000 were injured.

The Kenyan President, Daniel arap Moi, has declared five days of national mourning.

In the Tanzanian capital Dar es Salaam, eight people died in a similar bomb near the US embassy just minutes after the Nairobi attack.

Teams of US investigators are in Nairobi to search for evidence to track the culprits.

The former US ambassador to Kenya, Smith Hempsdown, 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."

Military engineers with heavy lifting equipment are controlling the rescue operation around the Kenyan embassy.

International terrorism expert Dr Neil Livingstone suggests the bombers may be state-sponsored

An Israeli team with expertise in rescuing people from bombed buildings has also been called.

The rescue effort has been painstaking. Rescuers were able to communicate by radio with four people trapped in the rubble.

Food and medical supplies are coming in

A man, whose cries were heard in the wreckage of the Co-operative Bank, next to the Nairobi embassy, died after rescuers spent four hours clearing debris to find him.

Others were believed to be trapped in the remains of the ground floor.

Eight US embassy staff or citizens were killed in the blasts. Five others are still unaccounted for.

Correspondent Cathy Jenkins says Nairobi's hospitals are struggling to cope with the injuries.

The US President, Bill Clinton, 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.

Some osurvivors were flown to South Africa for treatment

The US Under Secretary of State, James Pickering, said there had been no specific threats before the bombs, although earlier in the week a group known as the Islamic Jihad had made unspecified threats.

There are also unconfirmed reports that one man was arrested in Nairobi in connection with the bombing.

The Kenyan Trade Minister, Joseph Kamotho, and US ambassador Prudence Bushnell both suffered minor injuries in the Nairobi blast.

They were meeting at the Co-operative Bank building which took the full force of the blast.

The US embassy next door was also extensively damaged, with bomb-proof doors ripped off.

Flying debris was responsible for the majority of the injuries.

In Dar es Salaam, at least five people died when a car bomb destroyed two thirds of the US embassy.

Cranes were brought in to free people trapped in the rubble.
