Anti-government protesters in Thailand have placed symbolic padlocks on the doors of several state-run offices, continuing a week-long campaign to paralyze the administration of Yingluck Shinawatra.

Authorities, meanwhile, continued their hands-off approach to the protesters Saturday in an effort to avoid violence in the country's increasingly tense political conflict.

The opposition-led protesters have urged followers to ratchet up a campaign that has so far included seizing the Finance Ministry, turning out power at police headquarters and camping out at a sprawling government office complex.

Saturday's marches started off at the headquarters of two state telecommunications agencies, TOT and CAT Telecom, where protesters padlocked the front doors.

Protesters say they will seize key government offices Sunday, including several ministries and the prime minister's office.
