New York, Sep 11 (DPA) UN Secretary General Ban Ki-moon condemned the firing of two missiles into Israel Friday, saying the UN peacekeeping mission in southern Lebanon will investigate the incident.

He called on all parties to exercise restraint.

'The parties must fully adhere to Security Council resolution 1701 (passed in 2006) and respect the cessation of hostilities agreement,' Ban said in a statement.

The resolution ended the hostilities between Hezbollah and the Israeli defence forces and called for disarming the militias in southern Lebanon.

Lebanese security and Israeli military officials said unidentified militants in southern Lebanon fired two rockets into Israel, triggering retaliatory artillery. No casualties were reported.
