Opposition MPs in Taiwan have thrown pig guts and entrails at Premier Su Tseng-chang as he spoke in parliament.
They were protesting his policy to ease restrictions on the import of US-produced pork containing the food additive ractopamine.
As Su was about to approach the podium in parliament, he was shouted at by opposition Nationalist Party (KMT) lawmakers holding protest signs.
Then, during Su's address, some angry MPs threw pieces of pig guts and offal at him.
Su and some lawmakers from the ruling Democratic Progressive Party (DPP) - who tried to form a protective cordon around the premier - were hit by pieces of pig skin, guts or offal.
The premier eventually managed to finish his address in about five minutes.
In a state of chaos, some lawmakers exchanged punches with their colleagues.
Two lawmakers even wrestled each other on the ground.
The Taiwan government announced in late August that US pork products containing ractopamine residues will be allowed to enter the local market starting in January next year.
Opponents claimed the policy was made as an incentive to help advance trade deals with the US.
The ruling DPP condemned the KMT's actions in parliament.
KMT chairman Johnny Chiang late on Friday said the pork policy lacks explanation.
"If we don't strongly protest, then it is the start of tolerating an autocracy," Chiang said in a statement.
