Hundreds of protesters in Thailand forced their way into the army headquarters in Bangkok, on the sixth day of anti-government rallies.
The protesters broke open a gate, held a rally in the compound asking for the army's help in their campaign, and later withdrew without confrontation.
On Thursday, PM Yingluck Shinawatra called for an end to the demonstrations after surviving a no-confidence vote.
But protest leader Suthep Thaugsuban has rejected her appeal.
"We will not let them work anymore," the former senior opposition lawmaker said in a speech late on Thursday.
On Friday at least 1,000 protesters forced their way into the army headquarters compound, but did not enter any buildings.
The BBC's Jonah Fisher, who was at the scene, said protesters were massed on a lawn listening to speeches from leaders on a stage they had erected.
They urged the army to come out in support of the demonstrators. "We want to know which side the army stands on," Reuters news agency quoted one protester as saying.
