BOMB DISCOVERED BEFORE VISIT OF SEN. WELLSTONE, AMBASSADOR

Police discovered a roadside bomb outside a town hours before a U.S.
senator and U.S. ambassador were to visit, a Colombian police commander
said today.

Sen. Paul Wellstone, D-Minn., and U.S. Ambassador Anne Patterson were the
likely targets, Police Col. Jose Miguel Villar said.

But a State Department official in Washington said Patterson told
department officials by telephone that she did not see it as an
assassination attempt. Another State Department official, also asking for
anonymity, added that it is not unusual for such devices to be found in
Barrancabermeja, considering the town's reputation for violence.

A statement released late this morning by Wellstone's St. Paul office read:
``There's no evidence at this point of which we are aware that either the
senator or the ambassador were targets.'' Wellstone was on his way back to
the United States, the statement added.

Hours before the two U.S. officials flew into Barrancabermeja on Thursday,
police discovered two shrapnel-wrapped land mines alongside the road
leading from the airport to the town and arrested a suspected rebel, Villar
said.

The land mines each carried a 6.6-pound explosive charge, were attached to
cables and a detonator and were ready to be set off, Villar said in a phone
interview from Barrancabermeja, 155 miles north of Bogota, the capital.

Bernardo Alvarez Duarte, a suspected member of the rebel National
Liberation Army, or ELN, was arrested at the site, Villar said.

``If the bomb had gone off, it could have caused immense damage,'' Villar
said. ``It would have spread shrapnel over a wide area and could have taken
out 10 or 15 people.''

Patterson said she had received sketchy reports about the bomb as the
delegation departed Barrancabermeja.

Many residents of Barrancabermeja had known the U.S. delegation was going
to arrive. But security forces had kept confidential plans to transfer the
party from the airport to the town by helicopter. Even if the bombs had
exploded, the delegation would not have gone anywhere near them.

Villar said the Americans were probably the target of the bomb, but he
could not absolutely confirm it. Alvarez, the arrested man, was being
questioned for further information.

Washington supports the Colombian military in its fight against the ELN and
a bigger rebel group, the Revolutionary Armed Forces of Colombia, or FARC.

Barrancabermeja is the most violent town in Colombia, with almost 500
politically related murders this year alone, according to human rights
activists. Right-wing paramilitary squads and rebels have been preying on
the townspeople and fighting for control of the region.

Wellstone, a second-term senator and a member of the foreign relations
committee, arrived in Colombia on Tuesday night and was departing today. He
visited Barrancabermeja to lend support to human rights activists there.

On Thursday, Wellstone and his delegation were sprayed with a mist of
herbicide as they watched the Colombian National Police demonstrate a new
approach to fumigating coca, the raw product used to produce cocaine.
Police officials said it was an accident, blaming the wind for blowing the
chemical, which they said posed no risk to humans.
