International judges ordered the arrest of Moammar Gadhafi on Monday for allegedly murdering Libyan civilians who rose up against him, as NATO warplanes pounded his Tripoli compound and world leaders stepped up calls for the Libyan leader to resign.

The International Criminal Court said Gadhafi, his son Seif al-Islam Gadhafi and his intelligence chief Abdullah al-Sanoussi are wanted for allegedly orchestrating the killing, injuring, arrest and imprisonment of hundreds of civilians during the first 12 days of an uprising to topple Gadhafi from power, and for trying to cover this up.
