Tanks head for central Bangkok, reasons unknown

BANGKOK, Sep 19 (Reuters) More than 10 tanks blocked roads around Thailand's government headquarters in Bangkok today, Reuters witnesses said and Army television broadcast images of the royal family and songs associated in the past with military coups.

Government officials said Prime Minister Thaksin Shinawatra, in the middle of a political crisis fomented by a street campaign against him, planned to return from New York on Thursday, a day earlier than scheduled. They gave no reason.
