US drone strikes rise drastically under Donald Trump
In March, Trump gave the US military authority to carry out airstrikes without notifying the government in regions designated as areas with "active hostilities."
Yemen has come under regular US drone strikes, with Washington claiming to be targeting al-Qaeda militants while local sources say civilians have been the main victims.
The London-based NGO noted that the number of strikes doubled in Somalia and tripled in Yemen since Trump began his term in January 2017.
“In Somalia, the Obama administration had officially designated the al-Shabab group as an al-Qaeda affiliate at the end of November 2016, essentially widening who could be targeted. But there was no increase in strikes until July 2017, with all but two of this year’s 32 strikes carried out since then,” it added.
