At least six people were killed and 40 wounded in an apparent suicide attack on a number 4 bus in Tel Aviv.

The blast ripped through the bus as it stood at a station on Tel Aviv's Allenby Street around 12:50 Thursday. Police suspect that a suicide bomber detonated himself inside the bus shortly after getting on.

The bus blew up near the intersection of Allenby Street and Rothschild Boulevard, by the Beit Knesset Hagadol synagogue on Allenby.

Preliminary reports from the Magen Adom ambulance services reported a large number of casualties, at least 40, not including people suffering from anxiety and minor wounds.

The police say there were "hot" warnings of terror attacks inside Israel. They ask drivers and pedestrians to avoid the area.

The bus blew up next to stations of bus numbers 24, 25, and 4, the radio reported.

Ronen Kotler, Magen David Adom said that all the casualties at risk have been sent to hospital. At least four of the evacuated have been mortally wounded and another 10 are in serious condition, Magen David said.

The Bezeq phone company has asked people to avoid calling businesses and homes in that area to avoid tying up lines that the rescue services might need.

The wounded have been evacuated to several hospitals. Their emergency numbers: Tel Hashomer: 1255-131

Ichilov: 1255-133
Beilinson: 1255-134
Wolfson: 1255-135.

Resumption of terror attacks

On Wednesday there were several attacks on Israelis. Three Israelis were killed in three separate attacks across the country.

For the first time in about a month and a half, a suicide bomber blew himself up at the Umm al Fahm junction, killing one police officer and injuring four others. The Islamic Jihad has claimed responsibility for that attack.

Earlier Wednesday, one Israeli was killed and another injured in a shooting attack near the West Bank settlement of Mevo Dotan north of the Palestinian city of Jenin. Also Wednesday, the slain body of an Israeli man was found just outside the West Bank village of Azzariyeh east of Jerusalem.
