Israel’s cabinet has extended the powers of a commission investigating its raid on a Gaza-bound flotilla in which nine Turkish activists were killed.
The five-man panel can now force witnesses to appear and testify under oath.
The head of the Israeli military, Defence Minister Ehud Barak and Prime Minister Benjamin Netanyahu have all agreed to appear before the panel, which includes former Northern Ireland politician, David Trimble
Israel says its commandos were enforcing a blockade necessary to prevent weapons from reaching militants in the Gaza Strip, and they only opened fire when attacked by activists.
Due to its limited scope, the inquiry is seen as unlikely to pose any political threat to the Netanyahu government.
