Mali said on Sunday that investigators were following "several leads" after 19 people were killed in an attack on a luxury hotel claimed by three Islamist militant groups. Islamist militants' most deadly strike on the West African country in years ended on Friday when Malian commandos stormed the Radisson Blue hotel in the capital, Bamako, after an eight-hour siege and freed 170 hostages. But two days after the attack, little more has been revealed on the identity of the attackers. On Sunday, the Massina Liberation Front, which has been blamed for previous attacks in southern Mali, became the third group to claim responsibility for the siege. Al Mourabitoun and al Qaeda in the Islamic Maghreb (AQMI) already had claimed responsibility. "Several leads are being followed. The hotel that was attacked is being combed through carefully," according to a statement on state television. A Malian intelligence agent said 13 foreigners were killed in the attack, including six Russians, three Chinese, two Belgians, an American and a Senegalese.
