KEY POINTS:
MADRID - Spanish police investigating the 2004 Madrid train bombings have not ruled out the possibility that more people were involved in the deadly attacks than those identified, the trial heard on Wednesday.
A police witness said that after finding fragments of 10 rucksacks and three bags which did not explode, police believe 13 people planted the bombs.
Each bag was packed with 10 to 13kg of explosives which the bombers detonated on four rush-hour trains on the morning of March 11, 2004, killing 191 people and injuring 1800.
Seven suspects blew themselves up almost a month after the attacks and four are on the run, one of whom police suspect died in a suicide attack in Iraq. A total of 29 people are on trial for involvement in the bombings.
Investigators have no evidence that more people were involved in the attacks, but cannot rule out that possibility, said the police witness, not named and giving testimony from behind a curtain for security reasons.
Investigators have previously said they found DNA from two or three people in cars and houses used by the plotters which is still unidentified.
The trial is expected to last until July.
