Israel has vowed to destroy the military capabilities of Hamas so that they don't face any threat from them in the future. An Israeli ground assault will mark a week since the war broke out last Saturday with Hamas launching a fierce rocket attack with hundreds of its operatives unleashing terror in Israeli border towns. Israel responded with airstrikes in Gaza, bombing out what they claimed were Hamas hideouts. However, the densely populated Gaza Strip dotted with building and narrow streets will pose heavy challenges to the tanks and armoured vehicles. The debris of bombed out building will also make it difficult for them to navigate through the Gaza City. Besides, several hostages are also being held in Gaza.
