NAIROBI, Kenya - Kenyan officials said security forces controlled nearly all of an upscale mall on Monday, two days after it was seized by members of a Somali terrorist group who invaded with guns blazing, killing at least 62 people.
Four thunderous explosions reverberated through a Nairobi neighborhood in the morning, raising fears for the lives of any remaining hostages still being held by al-Shabab, a Somali armed Islamic group linked with al-Qaida, in the Westgate Mall.
Three attackers had been killed in the fighting Monday, officials said, and more than 10 suspects arrested. Eleven Kenyan soldiers were wounded in the running gun battles. By evening, Kenyan security officials were claiming the upper hand.
"Taken control of all the floors. We're not here to feed the attackers with pastries but to finish and punish them," Police Inspector General David Kimaiyo said on Twitter.
Kenya's interior minister said the evacuation of hostages "has gone very, very well" and that Kenyan officials are "very certain" that there are few if any hostages left in the building.
Interior Minister Joseph Ole Lenku also revised the death toll to 62. Kenyan officials earlier said 59 people have died since the siege on Westgate Mall began on Saturday, while the Red Cross had put the toll at 68, then in a tweet lowered it to 62, saying some bodies had been counted twice.
Dark plumes of smoke rose from the mall for more than an hour after four large explosions rocked the upscale Westlands neighborhood. A person with knowledge of the rescue operation told The Associated Press that the smoke was rising up and out of a large skylight inside the mall's main department and grocery store, Nakumatt, where goods like mattresses may have been lit on fire.
Kenya Chief of Defense forces Gen. Julius Karangi said fighters from an array of nations participated in the attack claimed by al-Shabab.
"We have an idea who these people are and they are clearly a multinational collection from all over the world," he said.
Karangi said Kenyan forces were in charge of all floors inside the mall, though terrorists could still be hiding inside. Earlier witness reports had indicated that a woman was among the estimated 10 to 15 attackers. Lenku said that instead some male attackers had dressed up like women.
The four explosions were followed by volleys of gunfire, then a thick, dark column of smoke that burned for roughly 90 minutes. Military and police helicopters and one plane circled over the Nairobi mall, giving the upscale neighborhood the feel of a war zone.
On Sunday Kenyan officials announced that "most" hostages had been rescued. But no numbers were given. Kenyan officials have never said how many hostages they thought the attackers had, but have said preserving the hostages' lives is a top priority.
Kenyans and foreigners were among those confirmed dead, including British, French, Canadians, Indians, a Ghanaian, a South African and a Chinese woman. The UK Foreign Office said Monday it has confirmed the deaths of four British nationals.
From neighboring Somalia, spokesman Sheik Ali Mohamud Rage for al-Shabab - the militant group that claimed responsibility for the attack - said in an audio file posted on a website that the hostage takers had been ordered to "take punitive action against the hostages" if force was used to try to rescue them.
At the Oshwal Centre next to the mall, the Red Cross was using a squat concrete structure that houses a Hindu temple as a triage center. Medical workers attended to at least two wounded Kenyan soldiers there on Monday.
Al-Shabab said on a Twitter feed, an account that unlike some others appears to be genuine, that the attackers had lots of ammunition. The feed said that Kenya's government would be responsible for any loss of hostages' lives.
As the crisis surpassed the 48-hour mark, video taken by someone inside the mall's main department store when the assault began emerged. The video showed frightened and unsure shoppers crouching as long and loud volleys of gunfire could be heard.
The al-Shabab extremists stormed the mall on Saturday from two sides, throwing grenades and firing on civilians.
Kenya's Red Cross said in a statement, citing police, that 49 people had been reported missing.
Al-Shabab said the attack, targeting non-Muslims, was in retribution for Kenyan forces' 2011 push into neighboring Somalia.
Al-Shabab is an extremist Islamic terrorist force that grew out of the anarchy that crippled Somalia after warlords ousted a longtime dictator in 1991. Its name means "The Youth" in Arabic, and it was a splinter youth wing of a weak Islamic Courts Union government created in 2006 to establish a fundamentalist Islamic state in the East African nation.
Al-Shabab is estimated to have several thousand fighters, including a few hundred foreign fighters. Some of the insurgents' foreign fighters are from the Middle East with experience in the Iraq and Afghanistan conflicts. Others are young, raw recruits from Somali communities in the United States and Europe.
