Israeli Prime Minister Benjamin Netanyahu said Sunday he will seek to dismiss the head of the country's internal security service this week, deepening a power struggle between the men focused largely on who bears responsibility for the Hamas attack that sparked the war in Gaza.

After months of tension, Israeli Prime Minister Benjamin Netanyahu announced that he would seek to remove the chief of the Shin Bet security service, Ronen Bar.

The Israeli prime minister’s effort to remove the Shin Bet chief is raising concerns about whether he was seeking to undermine the agency’s independence.
