Hamas militants in Gaza continued to fire rockets into Tel Aviv and Jerusalem Thursday morning, and Israel resumed its air strikes.
These air strikes destroyed a six-story residential building in the middle of Gaza City.
The IDF says it's also preparing for possible ground operations.
The United Nations has warned that the two sides are getting close to a full-scale war.
Reports say the violence has killed least 67 Palestinians and seven people in Israel.
Hamas has reportedly fired more than 15-hundred rockets into Israel since Monday night.
