Twin bombings in a tense region This week’s bombings in the capital cities of India and Pakistan were just a day apart. They were nearly identical in damage and impact — about a dozen people were killed in each blast. There was nothing to directly connect the attacks. We don’t know yet who is responsible for the attack in India. A faction of the Pakistani Taliban claimed responsibility for the attack in Islamabad. But tensions between India and Pakistan are running so high that the explosions have been enough to raise worries that the two neighboring nuclear powers could again start a cycle of escalation like the one that unfolded in May. It’s a sign of just how on edge the region is — and also, perhaps, of how little it could take to spiral into violence again. A more restrained India India has long accused Pakistan of providing sanctuary and support to militants who wage violence on Indian territory. In recent years, Pakistan has made similar claims against India, saying that the government has a hand in supporting the forces fighting the Pakistani state. The regional dynamics have only grown more volatile and complicated since the Taliban returned to power in Afghanistan. The government of Pakistan supported the Taliban during its 20-year insurgency against the U.S.-backed republic in Kabul. Now, though, Pakistan accuses the Taliban of working with India to back militants who are staging attacks in Pakistan. Indian officials have been measured in their statements since the deadly blast on Monday in New Delhi, which killed at least nine people and wounded 20 others near a metro station in a crowded part of the old city. That’s in contrast to how much India raised the stakes this spring, after carnage at a tourist picnic spot in Kashmir, part of a region disputed by India and Pakistan. Gunmen identified Hindu tourists by their religion before killing them in front of their families, leading the prime minister, Narendra Modi, to blame Pakistan for harboring the attackers and to launch military strikes against its neighbor. Modi then declared that any future terror attack would be seen as an act of war. India is investigating the Delhi blast as an act of terrorism. But figuring out who is responsible could be complex. India has been on the radar of other terrorist groups, including the Islamic State. Pakistan under pressure The blast has shattered New Delhi’s sense of safety, increasing pressure on Indian officials. The same could be said for Pakistan, where at least 12 people were killed and 27 others wounded on Tuesday around lunchtime in a suicide bombing near the entrance of a heavily guarded courthouse in Islamabad. The Pakistani government has already been under pressure from a relentless wave of attacks by militants in its western regions near the Afghan border. On Pakistani television and in government statements, the Afghan Taliban government is now mostly referred to as “India-backed.” Last month, Pakistan struck two Afghan cities, including its capital, Kabul, while the Afghan foreign minister was visiting India. India’s foreign ministry rejected the claim as “baseless and unfounded.” Pakistan’s political and military leaders have ramped up inflammatory rhetoric against India since their four-day clash in May. That face-off gave a popularity boost to Pakistan’s army chief, Asim Munir, who yesterday secured expanded constitutional powers and lifelong legal immunity. Even though channels of communication and diplomacy between the two countries are at their lowest level in years, some are still urging calm. Maleeha Lodhi, a former Pakistani ambassador to the U.S. and the U.N., told us that while tensions remain high, she didn’t think the two countries were on the brink of something ominous. But the spring conflict showed how quickly things could escalate: India and Pakistan were on the verge of full-blown war before President Trump pressured the two sides to a cease-fire. And when the cease-fire was agreed to, Modi said the operations against Pakistan were merely paused, not concluded. MORE TOP NEWS Epstein emails allege Trump knew of his conduct Democrats in Congress released emails yesterday in which Jeffrey Epstein, the convicted sex offender who died in prison, wrote that President Trump had “spent hours at my house” with one of the victims of his sex trafficking ring. In one message, Epstein asserted that Trump “knew about the girls.” You can read the emails here. Hours later, Republican lawmakers released their own trove of 23,000 pages of documents from Epstein’s estate. Republicans have been trying to protect Trump, who was a friend of Epstein’s until the two men had a falling out. But they are also facing a demand from voters for a complete disclosure of Epstein’s interactions with powerful men. Trump has emphatically denied any involvement in or knowledge of Epstein’s sex-trafficking operation. The White House press secretary yesterday accused Democrats of trying to “create a fake narrative to smear President Trump.” OTHER NEWS Israel said it had reopened a border crossing into northern Gaza, a longstanding request from organizations trying to bring more aid into the territory.

How they’re trying to live longer … in China China has made longevity a national priority, pouring billions into research and commercial endeavors despite sometimes shaky science and extravagant claims. At a recent gathering in Shanghai, businesses hawked anti-aging creams and potions, goji berries, cryogenic and hyperbaric chambers and other devices that are supposed to slow aging. SuperiorMed, a health care company, runs what it says is the world’s biggest “longevity hospital” in Chengdu and promotes “immortality islands,” though it acknowledges that they do not exist yet. Lonvi, a longevity start-up in Shenzhen, has developed anti-aging pills based on a compound found in grapeseed extract, which some studies have linked to an increase in the life span of mice.
