DOHA, Oct 24 (Reuters) - Qatar's ruling emir said Israel should not be given a green light for unconditional killing

Sheikh Tamim bin Hamad Al-Thani, in his annual speech to open the Gulf Arab state's advisory Shura council, said the fighting between Israel and Hamas was a dangerous escalation that threatened the region and the world.

He added that Qatar will use conservative energy pricing in its general budget. (Reporting by Nayera Abdallah and Andrew Mills, editing by Ed Osmond)
