AMMAN, Ramadan 16, 1437, June 21, 2016, SPA -- Jordan's army chief of staff announced on Tuesday that the country's northern and northeastern borders with Syria were closed military zones, according to an army statement, Reuters reported. The order comes into immediate effect, just hours after six Jordanian border guards were killed in a suicide attack on their military post in a desolate area in the country's far eastern border area with Syria that also converges with the Iraqi border. --SPA 18:06 LOCAL TIME 15:06 GMT www.spa.gov.sa/w
