MANILA, Philippines, Safar 2, 1437, Nov 14, 2015, SPA -- Philippine forces went on the highest alert Saturday following the deadly attacks in Paris, in a bid to ensure the safety of President Barack Obama and other Asia-Pacific leaders who will gather in Manila for an annual summit next week, AP reported. National police chief Director-General Ricardo Marquez said extra security steps, including a gun ban in metropolitan Manila, will reinforce the security of thousands of delegates, including 19 heads of state, attending the Nov. 18-19 Asia Pacific Economic Cooperation summit at a convention complex by Manila Bay. No specific threat has been monitored anywhere in the country, but security was strengthened at airports, seaports, train stations and other public areas "to maximize deterrence against unforeseen events," national police spokesman Chief Superintendent Wilben Mayor said. --SPA 11:16 LOCAL TIME 08:16 GMT www.spa.gov.sa/w
