Israeli security officials have arrested a man who they believe was responsible for Wednesday's bus bombing in Tel Aviv.

The suspect is thought to have thrown the bomb on to the bus before it was detonated remotely.

The explosion left 27 people with injuries, just a few hours before a ceasefire deal was struck to halt fighting between Israel and Hamas.

Officials said the suspect was an Israeli Arab who came from the village of Taybeh in Israel, and that he had links with both Hamas and Islamic Jihad.

Micky Rosenfeld, spokesman for the police, said: "He admitted to carrying out the terrorist attack."

Several other Palestinians have also been arrested in connection with the attack.

The blast was the first bombing in Israel's business capital in six years, the last such attack taking place during Passover 2006, when a suicide bomber at a café killed 11 people.

It was the first bus bombing in Tel Aviv in more than 10 years.
