Five men were arrested in Bavaria after German authorities said they planned to use a vehicle to ram a Christmas market near Dingolfing-Landau to kill or injure as many people as possible.The detainees include an Egyptian imam aged 56, three Moroccan men aged 22, 28 and 30 and a 37-year-old Syrian; prosecutors said the suspects were placed in pretrial detention while investigators probe an Islamist motive and noted the ongoing trial of Taleb Jawad al-Abdulmohsen.Joachim Herrmann praised the "excellent cooperation between our security services" that helped to prevent the plot, which authorities linked to heightened concern after the Magdeburg vehicle attack that killed six and injured hundreds.
