Thailand's government has revoked the passport of ousted Prime Minister Thaksin Shinawatra in connection with protests that put the country into deeper political crisis.

If we believe the person who holds the passport is doing anything that could undermine the security of the nation, then we have the right to revoke the passport, said Tharit Charungvat, a spokesman for the foreign ministry.

That decision leaves the exiled former leader without any legal travel documents unless he can persuade another country to give him asylum.

The protests ended on Monday that left two dead and 123 people wounded when the government sent in troops to break up the protest.

Bangkok is now calm but under heavy security. The government has issued an arrest warrant for Thaksin who has been calling for his followers to launch a revolution in Thailand.

Mr. Thaksin, who won two general elections, was overthrown by a military coup in 2006. He has been living mostly in Dubai.

The government says it has been in talks with other countries and Interpol to try to get him sent back to Thailand where he has been sentenced to two years in prison for abuses of power when he was in office.

Thai police now are still hunting 10 key protest leaders after four others surrendered.
