A man, reportedly mentally ill, attacked people with a shovel outside a Moscow church, injuring at least one paramedic, before being shot dead by a bystander. The incident appears isolated with no stated extremist motive, though details on the attacker's background and the bystander's legal status remain unclear. It highlights public-security concerns in Russia but has no immediate broader geopolitical or market implications.
