Munich, Rabi'I 21, 1437, Jan 1, 2016, SPA -- The terror alert level in the southern German city of Munich remains high, after a night during which two train stations had to be shuttered amid New Year's festivities because of worries about an attack, dpa cited authorities as saying Friday . "We still can't give an all clear. The increased terror alert continues for the time being," said a police spokesman. He noted that investigations are in high gear, but there have been no arrests to date. Two city train stations - including its central one - were shut down in the final hours of 2015 after police, acting on a foreign intelligence tip, issued a terrorism warning. Details about the exact nature of the threat and the people involved remain unclear. --SPA 12:45 LOCAL TIME 09:45 GMT www.spa.gov.sa/w
