Two Israelis were arrested overnight into Friday on suspicion of involvement in the explosions that took place on empty buses in two Tel Aviv suburbs.

The two suspects have been transferred to the Shin Bet security agency for interrogation, though a court has issued a gag order on further details of the affair.

On Thursday night, three explosive devices were set off on buses in Bat Yam and an additional device was found before it detonated in the nearby city of Holon. No casualties were reported. The Israeli army announced that three battalions will be transferred to the West Bank as reinforcements.
