News that the two suspects in the Boston Marathon bombings are brothers has sparked a great deal of interest in their family history and the relationship between the two siblings. But if they were indeed behind the assault, they wouldn't be the first brothers to plot or carry out such an attack. Here is a look at some of their predecessors in recent years:
In 2009, three brothers --ethnic Albanians from the former Yugoslavia -- were convicted of plotting to murder military personnel at Fort Dix, a base south of Trenton, N.J, along with two other men. Dritan Duka and Shain Duka received life in prison plus thirty years, while Eljvir received life imprisonment. The brothers claim they're innocent.
Last March, Mohammed Merah fatally shot a rabbi, three Jewish schoolchildren, and three French paratroopers in an attack in Toulouse, France before he himself was gunned down in a shootout with police. Merah, who claimed he was trained by al Qaeda, said the attack stemmed from France's ban on the full Muslim veil, the country's presence in Afghanistan, and his disgust over the treatment of Palestinians. His brother Abdelkader is being held in France on charges of complicity.
Late last year, Sheheryar Alam Qazi and Raees Alam Qazi were charged with aiding terrorists and planning to detonate a weapon of mass destruction in the United States (U.S. prosecutors say Raees wanted to retaliate against U.S. drone strikes in Afghanistan by blowing up a New York City landmark). The Florida-based brothers are both naturalized U.S. citizens from Pakistan.
In March, a Danish court convicted two Danish brothers from Somalia of planning a terror attack with Somalia's al-Shabab militants, and sentenced each to three and a half years in prison. Guleed Mohamed Warsame and Nuur Mohamed Warsame were found guilty of conspiring to send Guleed to a Shabab-run training camp in Somalia.
In January, two Bedouin brothers from the Negev confessed to a plot to fire rockets at Israel and stage a suicide bombing at a bus station in Beersheba. Mahmoud Abu Quider reportedly scouted the attack sites, while his brother, Samah, was to help carry out the assaults.
