The following reports compile all significant security incidents confirmed by New York Times reporters throughout Afghanistan. It is necessarily incomplete as many local officials refuse to confirm casualty information. The toll here does not generally include claims of insurgents killed by the government, because of the difficulty of verifying such claims. Similarly, the reports do not include attacks on the government claimed by the Taliban. Both sides routinely inflate casualties of their opponents.

Afghan casualties finally dropped this week, with 45 security force deaths and 38 civilians killed, by rockets, airstrikes and an I.E.D. The reduced casualty rate reflected the normal reduction in the war’s tempo during the winter months, although that reduction had been much delayed. Once again, the preponderance of Taliban attacks was in the west and north of the country, typically with insurgents overrunning small outposts. Meanwhile, the Islamic State affiliate in Afghanistan has been quiet for some time now.
