A key protest leader said on Monday that Thai anti-government demonstrators will end their sit-in at the prime minister's office compound and relocate to the capital's besieged airports. Chamlong Srimuang called on protesters who have occupied Government House since August 26 to "move to the airports to support our people there." The move does not represent a softening of the protest group's stance. Chamlong told supporters Monday that they should move because it was not safe to remain at Government House. Several grenades have been lobbed at protesters, wounding dozens.
