pThis week, we take a look at Western volunteers who travel to Syria to fight against jihadists. Some don't have any military training, but are willing to risk their lives to fight the militant group. pbr Also, the Islamic State (IS) group which has taken large parts of Syria and Iraq is now suspected of planting five bombs in Gaza. Its new target is Hamas' rulers. br And we bring you a dose of culture, including from Saudi Arabia where modern art is booming.
