Sunday first day of Ramazan in Arabia

Saudi Arabia has announced that the first day of the Muslim holy fasting month of Ramazan will be Sunday June 29 after the new crescent moon was not able to be seen on Friday. 
Other Arab and Islamic countries also announced that Ramazan will start on Sunday. These include Tunisia, Algeria and Libya, Bahrain, United Arab Emirates, Kuwait, Qatar, Oman, Egypt, Jordan, Sudan, Palestine, Indonesia and Malaysia. 
Yemen is the only country in the region that declared Saturday as the first day of Ramazan. 
Khaled al-Zaaq, member of the Arab Union for Space Sciences and Astronomy, had said that “it will simply not be possible to sight the crescent on Friday because on that day the moon will completely disappear from the skies before sunset.”
