A tribal chief in Yemen who says he was the target of a bomb attack on Tuesday in Sana'a has blamed Saudi Arabia for the incident.

The tribal chief, Sheikh Mohammed bin Shajeh, lives in a house close to where the bomb went off.

Three people, including a young boy, were killed in the attack.

Sheikh bin Shajeh said today that agents sent by Saudi Arabia had carried out the attack because he sided with Yemen in a border dispute between the two countries.

He said that an anonymous telephone caller had threatened to kill him earlier this month if he did not change his position in the dispute.

Correspondents say that Yemen has long contested Saudi Arabia's claim to three Red Sea islands and parts of the region known as the Empty Quarter, a vast area of desert with potentially lucrative oil fields.
