Police probing the Madrid terrorist attacks have found a van with detonators and an Arabic-language tape with Koranic verses - and officials don't rule out any line of investigation, Spanish Interior Minister Angel Acebes has said.

The van was found in the town of Alcala de Henares outside Madrid following a tip from neighbours.

On the front seat police found seven detonators and the tape, Acebes told a news conference.

"Because of this, I have just given instructions to the security forces not to rule out any line of investigation," he added.

He said the armed Basque group ETA remained the "main line of investigation".

Three of the four trains bombed originated in Alcala de Henares and one passed through it, the state rail company RENFE said.
