British police investigating Saturday’s attacks in London have detained a “number of people” after entering two properties in early morning raids in the east of the city. Police said officers from the Counter Terrorism Command unit had raided the properties and searches were ongoing in connection with attacks that killed seven people and injured more than 50 on Saturday night. British Prime Minister Theresa May will hold a meeting of the government’s emergency security committee on Monday to discuss the response to the third attack in Britain in less than three months.
