PLEASE NOTE: EDIT CONTAINS CONVERTED 4:3 MATERIAL
Police discovered large amounts of bomb making materials in a warehouse southwest of the Thai capital.
The substances found included over 4,000 kg of urea and 10 gallons of liquid ammonium nitrate.
Authorities had increased security across parts of the capital and tourist areas after the U.S. and Israel warned them of a possible attack.
The Thai prime minister said investigations were underway.

"No situation arose, but we're investigating anyway. We're investigating despite the fact that there was no bombing. We're following updated information about the suspect."
Last week, police arrested a Lebanese man, carrying a Swedish passport suspected of planning an attack.
Officials said he had links with Hezbollah, a Shi'ite Islamist group in Lebanon.
The suspect named as Atris Hussein, led police to the warehouse.
National police chief said he did not believe Thailand was the actual target of the attack.
(SOUNDBITE) NATIONAL POLICE CHIEF PRIEWPAN DAMAPONG SAYING(Thai):
"We are certain that we are cleared (of the attack threat). And we weighed our theory and believe we are just a by-pass location or a stopover for their attack material. So, with all the evidence that we have and with the intelligence reports, there is no real threat to our tourists spots such as Khao San road or any other spots. Anyway, we still aware of the threat and will not underestimate the situation."
The Lebanese suspect has not yet been charged with any offence.
