His Highness King Hamad bin Isa Al Khalifa left Bahrain Friday heading for Egypt to attend the 26th session of Arab League Summit at the invitation of Egyptian President Abdel Fattah Al Sisi. King Hamad will lead Bahrain's delegation in the two-day pan-Arab summit, scheduled to start Saturday in the Red Sea resort of Sharm el-Sheikh. The Saudi-led air strikes on Yemen's Houthi rebels are set to dominate the Arab summit which will consider forming a joint military force as several countries in the region suffer a state of security chaos.
