Speaking with reporters in Berlin Tuesday night, Prime Minister Ehud Olmert said Israel's current policy of restraint "is becoming harder and harder."

"I know how easy it is to return to violence," Olmert said, "but we are exercising self-restraint and are not retaliating." The prime minister pointed out that Arab terrorists from Gaza have attacked Israel more than 20 times with rockets since the ceasefire agreement was reached in late November. The latest attacks followed four days of quiet on the Gaza front.

Olmert was in Germany on his first state visit as prime minister. He met with the German leadership, including Chancellor Angela Merkel on Monday and Tuesday. Olmert is due to meet with his Italian counterpart and with the Pope in Rome on Wednesday.

There were no injuries reported in the five Kassam rocket attacks launched from Gaza late Tuesday evening. The rockets landed in open areas adjacent to towns in the western Negev.

Palestinian Authority sources in Gaza told Yediot Acharonot that the Islamic Jihad's Al-Quds Brigades, heavily linked with Lebanon's Hizbullah, launched the attacks. There was no denial or confirmation from the group itself. Earlier Tuesday night, Israel announced a series of sweeping raids that broke up an Islamic Jihad network in Samaria.

A Geocartographia poll released by Voice of Israel government radio shows that almost two-thirds of Israelis backed the Gaza ceasefire with PA terror organizations. Slightly more than half of respondents wanted the ceasefire extended to Judea and Samaria.

The November 27 ceasefire agreement called for an immediate withdrawal of Israeli soldiers from the Gaza area, where they had been operating against terrorists and rocket-launching cells. The PA agreed to halt all terrorist operations against Israel from the area; however, as noted, rocket attacks have not ended.
