Israeli authorities arrested an Israeli Arab on suspicion of planting a bomb in a Tel Aviv bus that wounded 15 people hours before Israel agreed a cease-fire with Hamas in Gaza, police and security officials said on Thursday.
The Arab citizen of Israel was detained on Wednesday night, they said. Also arrested, police said, were a number of Palestinians affiliated with Hamas and Islamic Jihad militants in the Israeli-occupied West Bank on suspicion of having recruited the Israeli Arab to carry out the bombing.
Police spokesman Micky Rosenfeld did not give names or an exact number of how many people were in custody.
He said the Israeli Arab notified his Palestinian handlers in the West Bank when the bomb was in place on the commuter bus, and they then detonated the device with a mobile phone.
"The investigation is still under way, and other arrests are expected," the Shin Bet internal security service said in a statement.
Wednesday's bus bombing had raised the possibility that Palestinians had slipped in from the nearby West Bank to carry out the attack.
