MOGADISHU, Sept 2 (Reuters) - An air strike in Somalia by U.S. armed forces targeted the leader of the Islamist militant group al Shabaab, Ahmed Abdi Godane, Somali and U.S. officials said on Tuesday, but they said it was unclear whether he was killed in the attack.
"We don't know that he's dead. But he was the target," one U.S. official told Reuters, speaking on condition of anonymity.
Other U.S. officials said they believed Godane was killed in the strike late on Monday against a location where senior members of the al Qaeda-linked group were meeting, but the U.S. government has not confirmed this yet or given further details.
If Godane were killed, it would be a major victory against the al Shabaab militants fighting the Western-backed government of Somalia, which is also supported by African Union troops.
Since taking charge in 2008, Godane has restyled the group as a global player in the al Qaeda franchise - a transformation that was highlighted when it killed at least 67 people in an attack on a Kenyan shopping mall in September last year.
The militants have also carried out guerrilla attacks in parts of the Somali capital Mogadishu, as well as in neighbouring Kenya and Uganda.
Godane's close associate, Ahmed Mohamed Amey, was killed by a U.S. air strike in January.
After the Westgate mall attack, Navy SEALS stormed ashore into the al Shabaab stronghold of Barawe, where a regional official said the latest air strike was also launched, but they failed to capture or kill their target then.
The U.S. Department of Defense said late on Monday that its forces had carried out the operation against al Shabaab and would provide more information "when appropriate". The Somali government and al Shabaab officials could not be immediately reached for comment.
"There was an air strike at a base where senior members of al Shabaab had a meeting last night," a senior intelligence official who gave his name as Ahmed told Reuters on Tuesday.
"So far Godane's death is a strong rumour that may or may not turn to be true. What we know is that the militants were bombarded. However, it is difficult to know how many of them or who particularly died," he added.
Abdiqadir Mohamed Sidii, governor of Lower Shabelle region in southern Somalia, where the strike occurred, some 245 km (150 miles) southwest of the capital Mogadishu, said he believed Godane and other senior al Shabaab members had been killed.
"We understand a U.S. drone killed Ahmed Abdi Godane and other seven senior members last night near Hawaay area around Barawe town," Sidii told Reuters by phone.
Sidii did not say how he got the information on the attack, given the location is in an area still under al Shabaab control.
Residents in Haaway said they heard loud explosions late on Monday in an area they described as a densely forested.
Al Shabaab, which aims to impose its own strict version of Islam, controlled Mogadishu and the southern region of Somalia from 2006 to 2011. It was forced out of the capital by peacekeeping forces deployed by the African Union.
African Union forces launched a new offensive this year to drive the Islamists out of towns and other areas they still control, in response to a surge in gun and bomb attacks in Mogadishu by the militants whose fighters have targeted legislators and the presidential palace.
