Translation of teletext:
Protestors arrested at KTH
Three people have been arrested and some 20 have been detained after a protest at the Royal Institute of Technology in Stockholm.
According to police they are suspected of for instance crime against masking ban, disobedience against law enforcement and vandalism.
Protestors at the scene declare to SVT that they have protested against Israels warfare in Gaza in connection with the fact that the Christian Democrats' party leader Ebba Busch visited the school.
Also at Lund University there are ongoing protests against the war in Gaza.
I don't think so. From the linked article:
You can see that in the video as well.
