The Israeli military says six Palestinians have been wounded in a suspected firebomb attack in the West Bank.

The six were traveling in a taxi Thursday night when the firebomb was allegedly thrown into the car. The military suspects Jewish extremist to be behind the attack.

Extremist settlers often attack Palestinians and their property in a campaign they call "price tag." It's meant to retaliate for either army action against settlers or Palestinian attacks. Several more firebombs were hurled earlier Thursday toward settler vehicles in the West Bank.

The military says it is still searching for the culprits.

Prime Minister Benjamin Netanyahu condemned the attack, saying Israel "will do everything to catch those responsible and bring them to justice."
