Amman  - Head of Hamas' politburo Khalid Mashaal claimed "unequivocal victory" Wednesday over Israeli forces in the Gaza Strip, saying it would pave the way for the "liberation of Jerusalem" and other Palestinian territories.

He also urged new US President Barack Obama and European leaders to take the "required lessons" from their countries' support to the "Israeli aggression".

Damascus-based Mashaal made the remarks in a recorded address screened by the Doha-based Aljazeera television network.
