Israeli airplanes on Saturday launched coincident raids at tens of targets in the Gaza Strip, witnesses and security source said.

The airstrikes targeted police and security centers run by Islamic Hamas movement, according to the initial information.

Columns of black smokes were seen across the Gaza Strip, with at least 10 pillars of smoke were seen clearly in Gaza city.

The strikes paralyzed the mobile telecommunication network and made it difficult to contact medical sources to check for casualties.
