Step-by-step explanation:
1. In response to the attack, Israel has declared war and launched “Operation Swords of Iron,” striking what it says are Hamas and Islamic Jihad targets in Gaza. It has also blocked supply lines of basic necessities to the Gaza population, including fuel and water.
2. Efforts to get humanitarian aid into Gaza are complicated by the fact that Hamas continues to use innocent civilians as human shields and is reportedly blocking roads to prevent Palestinians from moving to southern Gaza out of harm's way.
3. Hamas said it received support from Iran for the attack, which it says was in response to Israeli settler violence, the blockade of the Gaza Strip, the desecration of the Al-Aqsa Mosque in Jerusalem, as well as Israeli atrocities against Palestinians over the decades.
