JAKARTA, Indonesia (AP) — Thousands of Indonesian students resumed protests on Monday against a new law they say has crippled the country's anti-corruption agency, with some clashing with police.

Authorities blocked streets leading to the Parliament building in Jakarta, where 560 members of the House of Representatives whose terms ended Monday held their last session.

Clashes between rock-throwing students and riot police broke out in the evening when police tried to disperse the protesters, ranging from high school to university students, who attempted to reach Parliament after calm had largely returned to the country's capital over the past four days.

Protesters set fires to tires and pelted police with rocks, gasoline bombs and firecrackers near blocked streets. Riot police responded by firing tear gas and water cannons.

Similar clashes also occurred in other Indonesian cities, including in West Java's Bandung city and in Makassar, the capital of South Sulawesi province, where a student was badly injured on Friday after being accidently hit by anti-riot armor.

A protest also turned violent in President Joko Widodo's hometown of Solo city in Central Java, where an angry mob threw rocks at police, injuring at least four female officers in the head.

The demonstrators are enraged that Parliament passed the law reducing the authority of the corruption commission, a key body fighting endemic graft and which has been one of the most credible public institutions in a country where the police and Parliament are seen widely as being corrupt.

The protests have grown since last week and turned violent in some cities. At least three people, including two students in Kendari city on Sulawesi island, have died and several hundred were injured.

The death of the students sparked a national outcry, prompting Widodo to express his deep condolences and order the National Police chief to conduct a thorough investigation.

The protests, which underline Indonesia's challenge in changing its graft-ridden image, have threatened the credibility of Widodo, who recently was reelected after campaigning for clean governance.

He faced down riots in May by supporters of the losing candidate, former Gen. Prabowo Subianto, but those events were seen as partisan politics with limited support.

The new protests are not associated with any particular political party or group, and instead are led by students, who historically have driven political change. Student demonstrations in 1998 triggered events that led the country's longtime strongman leader, Suharto, to step down.
