A delegation of Canadian MPs and senators were forced to take shelter Sunday after a series of Hamas rockets were launched at the Israeli city of Tel Aviv.

Newfoundland and Labrador Liberal MP Gerry Byrne tweeted that Hamas rockets directed at the city forced him and the group of delegates out of their vehicles to take cover.

Byrne tweeted Israel's Iron Dome defence system half a kilometre away from his location was able to intercept most of the rockets.

CBC News has yet to make contact with the MPs in Israel.

This is the third time in a week the Canadian delegation was forced to take shelter during their visit to the country as guests of the Centre for Israel and Jewish Affairs.

Byrne, who represents the western Newfoundland riding of Humber–St. Barbe–Baie Verte, tweeted Saturday the group were forced into a bomb shelter during dinner. 

On Tuesday, Byrne and Labrador MP Yvonne Jones, along with senators Daniel Lang and Salma Ataullahjan, hid underground during an attack on Jerusalem.

Early Sunday, Israel launched attacks in Gaza as it widened its range of bombing targets to civilian institutions with special Hamas ties and launched ground troops in Gaza. More than 156 Palestinians have been killed in the attacks.
