COLOMBO, Sri Lanka (AP) — Tens of thousands of opposition supporters have marched in Sri Lanka's capital to demand the government step down, accusing it of corruption and selling national assets to foreign nations.

The activists loyal to former President Mahinda Rajapaksa walked along several main roads in Colombo on Wednesday, shouting slogans and holding placards. They later gathered near the president's office and launched a sit-in protest on a main road.

Rajapaksa's loyalists criticize the government for selling national assets to foreign countries, including the leasing of a sea port to China for 99 years.

The government was elected on a platform of good governance but its image was marred in 2015 by a central bank scandal that led to the resignation of a key minister.
