KABUL, Afghanistan — Twin bombings in Kabul on Monday killed at least 25 people, including nine journalists. It was the deadliest single attack involving journalists in Afghanistan since at least 2002, and one of the most lethal ever worldwide, according to the Committee to Protect Journalists.

A 10th journalist, from the BBC’s Afghan service, was shot and killed in a separate attack on Monday outside Kabul.

The bombings were the latest spasm of a conflict that began more than a decade and a half ago and shows no sign of ebbing.

In a two-stage attack, bombers detonated a first device during the morning rush and a second roughly 40 minutes later, killing emergency workers and journalists who had by then reached the site, officials said.
