COLOMBO, Sri Lanka (AP) _ A suicide bomber blew herself up Thursday, killing a driver and wounding two soldiers in northeastern Sri Lanka, a senior army official said.

The attack, blamed on Tamil Tiger rebels, took place near the government-controlled town of Trincomalee, 140 miles northeast of the capital, Colombo.

The woman jumped in front of a vehicle carrying the local army brigade commander, Col. Piyal Abeysekera.

The driver was killed while the officer and a soldier traveling with him were wounded, said the official, speaking on condition of anonymity.

A man whom an eyewitness identified as having ridden the same bicycle used by the suicide bomber was arrested by the army.

The Tamil Tigers, who have been fighting for a Tamil homeland in the northeast of the island nation, have a separate unit of fighters called the Black Tigers who carry out suicide bomb attacks. Many politicians and military personnel have been killed in suicide attacks since the insurrection began in 1983.

More than 61,000 people have died in the 17-year insurgency.
