Israel is ready to act with full force to stop missile attacks launched from the Gaza Strip, Prime Minister Benjamin Netanyahu said on Friday.

"No country could accept such attacks," Netanyahu told reporters ahead of his meeting with United States Defense Secretary Robert Gates in Caesarea.

The prime minister's comments come a day after a Grad rocket was launched towards Ashdod from Gaza in addition to three Qassam rockets which landed in the Negev. Thursday was another day of exchanges of fire in the area of the Gaza Strip, with five mortar shells landing on the Israeli side of the border.

The rockets resulted in the Israel Air Force launched two strikes on the Strip Thursday. It attacked a group launching Grad missiles in the morning, with the militants fleeing but the launcher successfully destroyed. In the evening, the IAF attacked an Islamic Jihad target described as a "weapons manufacturing site."

In addition to a drastic increase in rocket fire, a bomb detonated in Jerusalem on Wednesday that killed one and injured over 30.

Before meeting with Gates, Netanyahau promised a "tough reaction" to the bombing attack, adding that Israel would act "responsibly and wisely."
