BAGHDAD More than 100 people were killed in a suicide car bombing at a busy market in an Iraqi town on Friday, in one of the deadliest attacks carried out by Islamic State militants since they overran large parts of the country. 
  
 The blast brought down several buildings in Khan Bani Saad, about 30 km (20 miles) northeast of Baghdad, crushing to death people who were celebrating the end of the Muslim fasting month of Ramadan, police and medics said. 
  
 Islamic State, which controls large parts of northern and western Iraq claimed responsibility for the attack in the mixed eastern province of Diyala where Khan Bani Saad is located and said the target was "rejectionists", as the group refers to Shi'ite Muslims. 
  
 Angry crowds went on the rampage after the explosion, smashing the windows of cars parked in the street in grief and anger. Body parts were flung onto the roofs of nearby buildings by the force of the blast, police said. 
  
 "Some people were using vegetable boxes to collect children's body parts," said police major Ahmed al-Tamimi from the site of the explosion, describing the damage to the market as "devastating". 
  
 An officer from the Diyala police command said rescue crews were still retrieving bodies from under the debris so the death toll could rise. 
  
 The Diyala provincial government declared three days' mourning and ordered all parks and entertainment places to close for the rest of the Eid al-Fitr holiday to pre-empt any further attacks. 
  
 Islamic State said in a statement issued on Twitter that the attack was to avenge the killing of Sunni Muslims in the northern Iraqi town of Hawija, and that the suicide car bomber was carrying around three tonnes of explosives. 
  
 Iraqi officials declared victory over Islamic State in Diyala earlier this year after security forces and Shi'ite paramilitaries drove them out of towns and villages there, but the insurgents remain active in the province. 
  
 Security forces and militia groups are currently focused on the western province of Anbar, where they have been gearing up for an offensive to retake the mainly Sunni governorate - Iraq's largest. 
  
 The United Nations said earlier this week that nearly 15,000 people had been killed in the 16-month period up to April 30. 
  
 (Reporting by Baghdad Bureau; Writing by Isabel Coles; Editing by Andrew Heavens, Toni Reinhold) ||||| Baquba (Iraq) (AFP) - A car bomb blast claimed by the Islamic State group ripped through the crowded heart of an Iraqi town north of Baghdad Friday, killing at least 35 people, officials said. 
  
 The attack occurred in a market area of the predominantly Shiite town of Khan Bani Saad as people shopped on the eve of the Eid al-Fitr holiday marking the end of Ramadan. 
  
 "We have 35 martyrs and more than 70 wounded," said Mohammed Jawad al-Hamadani, a member of the Diyala provincial council in which Khan Bani Saad is located. 
  
 "The explosion was big, it caused a lot of damage," Raad Fares al-Mas, a member of parliament, said from nearby Baquba, the capital of Diyala. 
  
 Many women and children were among the victims, the officials said. 
  
 Footage aired on Iraqi television showed devastation around the bomb site, with several buildings completely gutted by the blast and debris strewn over a huge area. 
  
 The wounded were being attended to on the street as residents walked about in the chaos holding their heads, imploring God and screaming in horror.

 Six hours after the blast, rescuers were still pulling bodies from the wreckage, a police officer said. 
  
 Khan Bani Saad is less than 20 kilometres (12 miles) from Baghdad's sprawling northern neighbourhood of Sadr City. 
  
 Sunni Muslims began marking Eid al-Fitr on Friday but Iraq's majority Shiite community will start their celebrations on Saturday. 
  
 Markets are usually packed in the days before the holiday as people preparing for large family gatherings shop for food and clothes. 
  
 - Jihadist claim - 
  
 The Islamic State group issued a claim on jihadist forums saying the blast was caused by a suicide car bomb, one of their biggest such attacks in months. 
  
 "Our brother Abu Ruqayya al-Ansari advanced with his car loaded with almost three tonnes of explosives in the middle of a gathering for Rafidha militias," the claim said. 
  
 Rafidha is a term IS uses disparagingly to refer to Shiite Muslims. The group often says its car bomb attacks target Shiite militia members even when mostly civilians are killed. 
  
 The office of Diyala Governor Muthanna al-Tamimi issued a statement declaring three days of mourning across the province and cancelling Eid al-Fitr festivities. 
  
 The Islamic State group also claimed a deadly car bomb attack that took place Tuesday in Khalis, another town in Diyala just 30 kilometres (18 miles) north of Khan Bani Saad. 
  
 Baghdad announced in January that Iraqi forces had "liberated" Diyala, significant parts of which had been overrun by IS after the jihadists launched a brutally effective offensive last June. 
  
 The jihadists no longer have fixed positions there but have reverted to their old tactics of planting car bombs, carrying out suicide operations or hit-and-run attacks. 
  
 The United Nations said earlier this month that more than 15,000 civilians have been killed between the start of Iraq's latest armed conflict in January 2014 and April 2015. |||||
Output:
A suicide bomber struck at an Iraqi market today, but seldom have such attacks been so deadly: Reuters puts the death toll at more than 100 and reports that the Islamic State claimed responsibility, boasting that the vehicle used in the blast had 3 tons of explosives. The explosion brought down multiple buildings in the town of Khan Bani Saad, northeast of Baghdad, which AFP notes is predominately Shiite. Victims had packed the market to gather food in preparation for the end of the fasting month of Ramadan. "Some people were using vegetable boxes to collect children's body parts," says a police major.
