There has been an explosion on a bus in Israel's commercial capital Tel Aviv, police say, amid continuing exchanges between Israel and militants in Gaza.

There are at least 10 injuries in what police called a "terrorist attack".

The incident comes as Israel continued its strikes on Gaza, including a key compound of the Hamas government, and militants fired more rockets at Israel.
