In short:

A day after exploding pagers caused mass casualties in Lebanon, walkie-talkies used by members of the Hezbollah militant group detonated.

The Lebanese health ministry said 20 people were killed and hundreds were injured.

What's next?

Israel has not commented on the blasts, but Defence Minister Yoav Gallant said it was entering a "new phase" of war focused on the country's northern border with Lebanon.
