Fighting in Afghanistan resumed with 31 Afghans, mostly militants, killed in the insurgency-battered Asian country on Sunday after a three-day ceasefire observed with the start of Eid al-Fitr on Thursday to enable celebrations of the end of the Muslim fasting month Ramadan, officials said.

Mohammad Zaman Hamdard, the spokesman for provincial police in the southern Helmand province, has accused the Taliban militants of violating the ceasefire, saying the Taliban fighters attacked security checkpoints on Friday, the second day of the Eid al-Fitr festival, the Xinhua news agency reported. Hamdard said that the security forces after the end of the three-day truce targeted the militants from the ground and air on Sunday killing 21 militants and injuring 13 others.
