Arab League Secretary General Amr Moussa has called on Israel, which believed to be the sole possessor of nuclear weapons in the Middle East, to join the Nuclear Non-Proliferation Treaty (NPT).

Moussa made the call on Thursday after a meeting with Syrian President Bashar al-Assad in Damascus.

The two sides discussed the importance of collective efforts to finalize an Arab draft resolution concerning the Israeli nuclear potentials, and submit to the 54th Session of the International Atomic Energy Agency in Vienna on September 20, a Press TV correspondent reported.

"Israel has not jointed the Non-Proliferation Treaty, there is the consistence today that the Middle East region should be free of Weapons of Mass Destruction and if Israel is considered an exception that will not be archived," Moussa told reporters in Damascus on Thursday.

”In the light of the international meeting regarding reviewing the Non-Proliferation Treaty, there are decisions on the importance of Israel’s joining the treaty for the Middle East to be a nuclear-free zone,” he added.

Citing comments by British security experts, Jane’s Defense Weekly has recently revealed that Tel Aviv is currently in possession of between 100 and 300 nuclear warheads.

However, Tel Aviv maintains a policy of deliberate ambiguity on the matter and has so far refused to sign the NPT.

Moussa and Assad also reviewed the situation in the occupied Palestinian territories and the Israeli-imposed blockade of the Gaza Strip.

In a separate meeting with Hamas leader Khaled Meshaal, Moussa urged Palestinian groups to immediately end their internal divisions and stressed on Palestinian unity.

"Hamas is very keen to overcome obstacle to achieve reconciliation as soon as possible, we are ready for that and we hope the all parties to respond," Meshaal told reporters after the meeting.
