The six were arrested in the northern Asturias region and include a security guard who worked at the coal mine from which the 200 kilograms of explosives used in the attack were stolen, Interior Minister Jose Antonio Alonso said.

None of the six have been officially charged with a crime, Mr Alonso said. The brother-in-law had been arrested once before on March 27, but was released after questioning.

The arrest was part of raids that also led to yesterday's detention in Belgium of 15 people, mostly Palestinian, Jordanian, Moroccan and Egyptian. Four of those detained were charged with preparing terrorist attacks, but the target of the alleged plot was unclear, Belgian officials said.

The other suspects were either released or turned over to immigration authorities.

Belgian police said the 15 were not likely involved in the Madrid attack.

Meanwhile, the death toll in the train bombings was quietly reduced by one to 190 because a fetus killed in the attack was not considered a person, Spanish officials confirmed overnight.

But the officials said the figure was expected to rise again soon to include the death of a newborn whose mother was injured in the bombing.
