Israel’s anti-government protest movement launched a series of major disruptions on Monday, including an attempt to sow chaos at the international airport, over a renewed official attempt to weaken the judiciary.

The standoff coincides with an unusually fierce Israeli military operation in the northern West Bank that killed nine Palestinians and injured several dozen, some critically. Such operations depend partly on military reservists, some of whom are stepping up their role in the protests.

The police arrested four people at Ben Gurion Airport after a "violent disturbance” that saw officers attacked, according to a statement around 6 p.m. local time.
