KABUL, Afghanistan — In downtown Kabul, from a large mural painted on blast walls at the end of a busy shopping street, the piercing eyes of Komal Singh, now a fourth grader, peer out at the narrow junction.

For the past couple of years, the mural has carried an anticorruption message: “Bribetakers are not hidden from the eyes of God and the people.” Now, that mural carries a further, unwritten reminder: Another Afghan child is deprived of a father.

On Monday, Komal traveled to the eastern city of Jalalabad with her mother, Preeti, sister Pari and brother Prince to cremate her father, Rawail Singh, who was among the 19 people killed this weekend in a bombingoutside a compound where President Ashraf Ghani was holding meetings.
