TAIPEI: Taiwan's leader called for calm after violent protests over pension reforms outside parliament Wednesday saw scores of demonstrators scuffling with police and politicians.
The rallies were staged as parliament began reviewing controversial bills which are designed to stop the struggling pension system from collapsing but are expected to hit nearly 500,000 civil servants and teachers.
Several lawmakers and politicians said they were pushed, punched and had water splashed on them as they tried to enter the legislative complex in central Taipei, which was guarded by barbed-wire barricades and a heavy police presence.
President Tsai Ing-wen vowed to press ahead with the changes despite a recent string of protests and said her government would not tolerate violence.
"Intentionally causing conflicts will not deter the (government's) determination for reforms... our urgent task is to bring the pension system back from the brink of bankruptcy," she told reporters.
The Taipei police department said one person had been arrested for attacking a media van while 24 other protesters were being investigated for violence, which led to seven officers being injured.
Anger has been mounting among public-sector workers and retirees as the government unveiled draft bills aimed at reducing their pensions and phasing out a special savings rate for them which pays 18 percent interest.
The government has warned that various pension funds are likely to go bankrupt within three to 14 years unless the system is overhauled.
More than 100,000 civil servants, teachers and servicemen demonstrated last year against the planned reforms -- the largest street protest since Tsai became president.
There was also chaos inside parliament Wednesday as opposition lawmakers temporarily seized the podium and demanded the government hold public hearings on the issue.
The pension issue is the latest challenge to Tsai, who has seen her popularity ratings fall rapidly since taking the helm in May last year as her government tackles a range of domestic issues -- from gay marriage to judicial reform.
The Pension Reform Oversight Alliance, an organiser of Wednesday's protests, criticised the government's "rough and irresponsible" methods and vowed to stage bigger demonstrations.
"The Tsai government blames us but it is their incompetence that is forcing many people, not just civil servants and teachers, to take to the streets," said Lee Lai-hsi, a spokesman for the alliance.
Last December parliament plunged into chaos with opposing lawmakers brawling in the chamber while labour activists set off smoke bombs outside in protest at proposed holiday cuts.
Taiwan's parliament was once notorious for mass brawls among lawmakers and has been a site for frequent protests.
In 2014, students and protesters stormed parliament to oppose a China trade pact and occupied its main chamber for weeks in the so-called "Sunflower Movement."
Taiwan's pension schemes vary for different occupations. Public-sector retirees typically receive more generous packages than other workers.
