RIYADH - Powerful Saudi Crown Prince Mohammed bin Salman condemned the attack on an Egyptian mosque that killed more than 300 worshippers and said it would galvanize an Islamic military coalition he convened in Riyadh on Sunday.
Top defense officials from some 40 Muslim-majority countries met for a summit aimed at countering "terrorism."
"(The attack) was a very painful occurrence and must make us contemplate in an international and powerful way the role of this terrorism and extremism," Prince Mohammed said.
