The complicated effort to assign blame for the worst offshore oil spill in U.S. history took another legal twist Monday when BP went to court to accuse Halliburton of "destroying damaging evidence about the quality of its cement slurry that went into drilling the oil well," The Associated Press writes.

"The owner of West Virginia's Upper Big Branch coal mine is reportedly ready to pay $209 million to settle civil and criminal claims resulting from the explosion that killed 29 people last year," NPR's Howard Berkes reports.

He adds that:

A suicide bomb detonated today in the midst of a crowd of Shiite worshipers in Kabul has left about 50 people dead. NPR's Quil Lawrence reports from there that witnesses say dozens of bodies were scattered around the gate of a mosque.

Al-Jazeera says the Afghan ministry of health reports more than 100 people were injured.

Another four people were reportedly killed and more were injured in the northern city of Mazar-i-Sharif by a similar attack. Al-Jazeera adds that:

The head of the Federal Aviation Administration, who among other duties is in charge of the nation's air traffic controllers, was charged with driving while intoxicated Saturday night in Fairfax, Va., a suburb of Washington, D.C.

And Federal News Radio says Jerome "Randy" Babbitt has now been "placed on a leave of absence." The Associated Press reports that the leave was "at Babbitt's request."
