Suicide Bombers Strike in Afghanistan During Hagel's Visit

At least 18 killed

KABUL, Afghanistan (AP)—Militants staged two suicide attacks that killed at least 18 people on Saturday, the first full day of U.S. Defense Secretary Chuck Hagel's visit to Afghanistan. They were a fresh reminder of the challenges posed by insurgents to the U.S.-led NATO force as it hands over the country's security to the Afghans.
