British Prime Minister Theresa May today expressed regret for the 1919 Jallianwala Bagh massacre by the British in India but stopped short of a full apology. “We deeply regret what happened and the suffering caused,” may told the British parliament, as India prepares to mark the 100th anniversary of the killings. Jeremy Corbyn, leader of the main opposition labour party, called for “a full, clear and unequivocal apology”.
