Twenty-one people injured in Tel Aviv

Twenty-one people have been injured in a "terrorist attack" on a bus in Israel's commercial capital Tel Aviv, Israeli officials say.

After the bus explosion, huge blasts were heard in the Gaza Strip as the Israeli bombardment of the Palestinian territory continued, the BBC reported.

Eleven people were killed in Gaza on Wednesday, the health ministry said.

Efforts are continuing to broker a truce between Israel and the Hamas movement which runs Gaza.
