June 10 (UPI) -- Terrorists "deliberately and knowingly targeted" civilians during the holy month of Ramadan resulting in a high number of innocent people killed, the United Nations said Monday.
The attacks include the May 8 attack in Kabul, the May 24 assassination of a religious scholar in a place of worship, the May 27 and June 3 attacks that targeted civilians and the June 2 attack against Shia students.
"I condemn these deliberate attacks on civilians that signal a disturbing intent to spread fear; they delegitimize the perpetrators, depriving them of any claim to represent the people of Afghanistan," said U.N. Secretary-General's Special Representative for Afghanistan Tadamichi Yamamoto. "It is crucial that all respect their obligations under international law to protect civilians."
The attacks amount to war crimes and crimes against humanity, the United Nations said.
The militant group is planning attacks against Western countries, U.S. and Afghan security officials said.
The Islamic State has more sophisticated military tactics and strategy than the Taliban fighters, who have been the primary enemy in Afghanistan. In particular, the Islamic State is known for attacking civilians.
