KABUL: Afghanistan has launched new attacks on Pakistan’s military bases, the Afghan defense ministry said on Saturday, as cross-border clashes escalated between the neighbors after months of tension. The latest flare-up erupted after Pakistan’s airstrikes on Afghan territory last weekend triggered a retaliatory offensive from Afghanistan along the border on Thursday. The two countries have engaged in tit-for-tat attacks since, marking the most serious development in ongoing tensions between the two countries, which agreed to a ceasefire last October following a week of deadly clashes.
