Defense Minister Ehud Barak ruled Monday against the reopening of Israel's goods crossings with Gaza on Tuesday, in wake of Sunday's mortar fire on Israel. Palestinian gunmen fired a mortar shell at Karni crossing on noon Sunday. The rocket landed in an open area near the crossing causing no injuries or damage. Barak's order came just 48 hours after Israel reopened the crossings, in accordance to the ceasefire agreement brokered with the militant groups in the Gaza Strip. Video courtesy of infolive.tv Sunday saw a another violation of the truce, as Palestinian snipers fired at farmers at Kibbutz Nahal Oz. No injuries or damage were reported in the incident, which was the first of its kind since the ceasefire came into effect. Hamas Prime Minister Ismail Haniyeh blamed Israel for not keeping its end of the agreement, saying "maintaining the ceasefire is a national priority for the Palestinian people, but Israel has to life the siege on Gaza and reopen the crossings." Hamas spokesman Fawzi Barhoum reiterated, saying that "the facts on the ground prove Israel isn't interested in a truce," and adding that the ceasefire has reached it end. Prime Minister Ehud Olmert said recently that a truce "cannot be enforced in full immediately, and therefore Israel has and will show patience but that patience should not be misconstrued as weakness. If the ceasefire is violated, we will know how to react."
