BANGKOK - Anti-government protesters in Thailand's capital have resumed their tactic of besieging government offices, cutting off electricity to the prime minister's office compound and demanding that police abandon the premises.

The protesters, who are seeking to force the replacement of caretaker Prime Minister Yingluck Shinawatra's government before a February 2 election, threatened Thursday to force their way in if police don't leave.

In a previous confrontation, police withdrew from the compound to allow the demonstrators in without a fight. That withdrawal came after two days of increasingly violent standoffs.
