ON the night of March 22, a shooting incident occurred in a concert hall in Krasnogorsk, a suburb of Moscow, the capital of Russia. Russian authorities have classified this incident as a terrorist attack, based on on-site investigations and situations. Following the incident, the extremist organization Islamic State-Khorasan Province (ISKP) claimed responsibility. Prior to this, major terrorist attacks occurred in Kabul, Afghanistan; Peshawar, Pakistan; and Kerman, Iran, with the same organization issuing responsibility statements. This series of terrorist attacks once again demonstrates that international terrorism remains rampant, and the international counter-terrorism efforts still have a long way to go.
