Anti-government protesters rallied in Thailand's capital Bangkok on Sunday, the 15th anniversary of the 2006 military coup, to demand the resignation of Prime Minister Prayut Chan-o-cha, a former army chief.
Police say about 2,000 people took part in the demonstration. They included supporters of former Prime Minister Thaksin Shinawatra, who was ousted in the coup and now lives in self-imposed exile.
Many of the protesters drove around central Bangkok on motorcycles and other vehicles, carrying banners that called for Prayut to step down.
One participant said people are starving as they have been unable to work due to the impact of the coronavirus pandemic on the economy.
He added that people want a new government that is not led by Prayut as prime minister.
In recent weeks, Thailand has confirmed more than 13,000 new daily cases of coronavirus infection, mostly due to the Delta variant.
People are growing increasingly dissatisfied with what they see as the government's slow moves to secure sufficient vaccine doses. They are also unhappy with its anti-infection restrictions on economic activities.
Young people have been staging anti-government rallies almost every day. Supporters of Thaksin, who remains popular among rural residents and others, have also been stepping up protests.
