The conflict between Israel and Hamas has worsened Friday. 16,000 Israeli reservists are mobilizing and many are moving toward the Gaza border as rockets are flying back and forth from Gaza to Israel. The Israel Defense Forces have made clear that they are prepared to put 30,000 troops on the ground if necessary.

This action signifies that there might be an impending ground war - something the region has not seen in several years.

Air raid warning sirens have been blaring throughout the day in Jerusalem as rockets rain down from Gaza, fired by Hamas terrorists.

In Gaza, the death toll has reached 20, and 235 are reported as being injured.

There was a military truce in place while the Egyptian Prime Minister was visiting Gaza, but it didn't last long.

Israel's major city, Tel Aviv, was attacked by rocket fire early Thursday morning in the most recent in a series of attacks over the past few days. This is the first time Tel Aviv - a vibrant city akin to Toronto or New York City, and home to 40% of Israel's population - has been targeted since the Gulf War in 1991.

This is the first time Hamas rockets from Gaza have reached as far as Tel Aviv, which suggests a huge expansion in Hamas' capabilities.

Jerusalem - a holy city for many religions including Jews, Christians and Muslims - has also been targeted for the first time ever. Hamas has taken responsibility for that attack, despite a significant Muslim Arab population in the city.

Israeli Prime Minister Benjamin Netanyahu has stated that the one think to be thankful for in this conflict is that other countries are standing behind Israel. Ban Ki-Moon, Germany and the UK have all publicly defended Israel's right to defend itself.

Prime Minister Stephen Harper and Foreign Affairs Minister John Baird have declared their support for Israel's retaliation.

"Canada condemns the terrorist group Hamas and stands with Israel as it deals with regional threats to peace and security."
