United States air strikes rampaged an al-Shabaab training camp in Somalia, killing more than 150 militant fighters. The Pentagon informed on Monday that these militants were planning to launch a massive attack on African or US personnel.

According to Navy Captain Jeff Davis, these militants posed an “imminent threat” to both US and African Union Troops operating in the war-torn country of Somalia. The air strikes included the use of both manned and unmanned aircraft.

The official also said there were no civilian casualties in the strike but they were still assessing the situation. The site where the attack took place is called Raso Camp in Somalia. The US had been watching it for several weeks, says WearTV.

“This was a group that was completing training to do a large-scale attack, and it would follow that when they concluded training, they would engage in a large-scale attack,” Davis said.

The strike on Raso Camp, approximately 120 miles north of Mogadishu, is the deadliest strike against al-Shabaab in a decade. This was the second US attack on the militant training facility in less than a month says The Washington Post.

It was last month when al-Shabaab claimed responsibility for a suicide bomber attack on the Emirati airline, coercing the plane to land in Mogadishu, Somalia.

 The Obama administration on Monday said reports on the number of people killed by drone strike outside conventional war zones will be presented. The reports will reflect data from 2009 when Obama became the president.

Lisa Monaco, Obama’s counterterrorism and homeland security adviser confirmed that the reports will come out in the coming weeks. This is, she says, a commitment to transparency for US actions overseas.

“We know that not only is greater transparency the right thing to do, it is the best way to maintain the legitimacy of our counterterrorism actions and broad support of our allies,” Monaco said.

Human rights group and legal organisations found this move to be an “important step.” According to ACLU’s deputy legal director Jameel Jaffer, there must be a broader consideration of the secrecy surrounding the drone campaign, says The Intercept.
