Afghans mourn those killed in horrific IS university attack

Afghanistan declared a national day of mourning Tuesday to honor the 22 people killed in a horrific attack a day earlier on Kabul University, which was claimed by the Islamic State group. Monday's brutal, hours-long assault was the second attack on an educational institution in the Afghan capital in as many weeks amid a soaring rise in violence and chaos across Afghanistan, even as Taliban insurgents and government negotiators hold peace talks in the Gulf state of Qatar. The Islamic State affiliate also claimed the earlier attack on Oct. 24 that killed 24 young students.
