Top Israeli security officials announced on Sunday that they will increase pressure on the government led by Hamas, recommending cutting all ties and not taking part in peace talks as long as Palestinian president, Mahmoud Abbas, and his militant group refuse to renounce violence.

Israel worries that the Hamas's contacts mainly with Russia and China, would reduce the effect of a boycott planned by Washington to weaken the group. According to the Israeli statement, "Israel will have no contact with the Palestinian Authority, which is a hostile entity, and will work toward preventing any entrenchment of the Hamas government's rule."

Israel will deal with Hamas only if it halts violence, recognizes Israel and accepts previous interim peace agreements. Also, the transfer of $55 million in tax revenues Israel collects for the Palestinians was suspended causing a serious damage to the Palestinian government's funds.

Despite the growing financial crisis Hamas is in and the international pressure, the group has rejected this ultimatum. Palestinian government spokesman, Asaf Shariv, said relations with Abbas would be limited, peace talks were out of the question and contacts would be permitted, in cases of humanitarian emergencies, such as bird flu.

Israel will not block the humanitarian aid for the Palestinian people as long as it does not reach the government. The U.S. and European Union, which consider Hamas a terrorist group, also cut off tens of millions of dollars in aid to the Palestinian Authority last week, worsening the financial crisis.

Palestinian Finance Minister, Omar Abdel, says this crisis is worse than he thought and does not have a plan for paying salaries to the government's 140,000 workers.
