Attacks on police posts, churches and a synagogue in Russia's North Caucasus republic of Dagestan have left 19 people dead, 15 of whom were police officers, along with four civilians. Five gunmen also died.

The apparently coordinated attacks targeted the cities of Derbent and Makhachkala on the Orthodox festival of Pentecost, with an Orthodox priest among those killed. Are there growing concerns about the threat posed by Islamist terror groups in the region?

Also in the programme: We'll hear from a former head of the Shin Bet - Israel's domestic intelligence service. How concerned is he about an all-out war between Israel and Hezbollah in Lebanon? And we'll hear from a composer who’s beginning a tour of works inspired by the changing sound of summer.
