Even as the Taliban and government signed on to the cease-fire, to mark the Islamic holiday of Eid-al-Fitr, violence continued in Afghanistan.

A three-day cease-fire marked by violent attacks — most claimed by the Islamic State group — ended Sunday in Afghanistan amid calls for renewed peace talks between the government and Taliban.

Taliban political spokesman Suhail Shaheen said the negotiating teams of the government and the Islamic Emirate, as the Taliban refer to their ousted regime, met briefly Saturday in the Middle Eastern State of Qatar. They renewed their commitment to finding a peaceful end to the war and called for an early start to talks that have been stalled, he said.

The U.S. has been pressing for accelerated talks as it withdraws the last of its 2,500-3,500 soldiers and NATO its remaining 7,000 allied forces.

Even as the Taliban and government signed on to the cease-fire, which was declared to mark the Islamic holiday of Eid-al-Fitr, violence continued unabated in Afghanistan. A bombing Friday in a mosque north of the capital killed 12 worshippers, including the prayer leader. Another 15 people were wounded. The Taliban denied involvement and blamed the government intelligence agency.

In a statement Sunday, the IS affiliate took responsibility for the mosque attack, saying its fighters planted an explosive device in “a worship place for disbelievers Sufis,” killing the “apostate Imam,” or prayer leader. The statement claimed 40 worshipers were wounded.

The IS also claimed it blew up several electrical grid stations over the weekend. That left the capital Kabul in the dark for much of the three-day holiday that followed the Muslim fasting month of Ramadan.


Islamic State Intensifies Attacks

In posts on its affiliated websites, IS claimed additional attacks over the last two weeks that destroyed 13 electrical grid stations in several provinces. The stations bring imported power from the Central Asian countries of Uzbekistan and Tajikistan.

The attacks have left nine provinces including Kabul with disrupted power supplies, said Sanger Niazai, a government spokesman. There was also concern that local warlords, demanding protection money from the government to safeguard stations in areas they control, may have been behind some of the destruction.

At least one local warlord was arrested last year after demanding protection money.
