"Hamas solely fights within the Palestinian territories and runs war just against the occupiers and will fight for its own nation only," Mashaal was quoted as saying by Palestine Today.
He also elaborated on his recent visit to Riyadh, and said, "Palestine needs support and help of all Arab and Islamic countries and Hamas doesn’t spare any efforts for (liberating) Palestine."
It was for the first time in the past three years that Mashaal paid a visit to Saudi Arabia.
Also in relevant remarks earlier this month, a senior Hamas member rejected that the recent visit of Mashaal to Saudi Arabia would affect the movement's relations with Iran.
"The visit of a delegation from this movement, including Khaled Mashaal, to Saudi Arabia and improvement of Hamas-Riyadh relations will not influence our ties with Tehran," Salah al-Bardawil said on Sunday.
He noted that Hamas will maintain its relations with all those who financially, military and spiritually support the movement.
Saudi Arabia has been striking Yemen for 120 days now to restore power to fugitive president Mansour Hadi, a close ally of Riyadh.
Hadi stepped down in January and refused to reconsider the decision despite calls by Ansarullah revolutionaries of the Houthi movement.
Despite Riyadh's claims that it is bombing the positions of the Ansarullah fighters, Saudi warplanes are flattening residential areas and civilian infrastructures.
The Monarchy's attacks have so far claimed the lives of at least 5,178 civilians, mostly women and children.
