Israeli warplanes have launched strikes in the northern Gaza Strip.

Palestinian witnesses say at least one Israeli missile struck a military compound, about 100 meters from the offices of Palestinian Authority President Mahmoud Abbas. The president was elsewhere when the attack occurred.

Palestinian sources say two guards were wounded when a rocket landed in the compound near a helicopter pad used by Mr. Abbas.

Israel says the strikes targeted opened areas used by Palestinian militants to fire rockets into southern Israel.

Militants fired at least nine rockets into Israel Tuesday, including one that Israel says landed dangerously close to a huge fuel storage facility near the port city of Ashkelon.
