Thousands of Kuwaitis have stormed parliament after police and elite forces beat up protesters marching on the prime minister's home to demand he resign.

"Now, we have entered the house of the people," said Mussallam al-Barrak, who led the protest along with several other MPs and youth activists also calling for the dissolution of parliament over alleged corruption.

The demonstrators on Wednesday broke open parliament's gates and entered the main chamber, where they sang the national anthem and then left after a few minutes.
