The Pentagon wants to cut the number of US peacekeeping troops in Egypt's Sinai Peninsula, partly because of the growing threat from the Islamic State group, an official said Tuesday.

About 700 US troops participate in a UN operation established after Israel and Egypt signed a 1979 peace deal and agreed for a Multinational Force and Observers (MFO) mission to monitor compliance.

The mission has historically been somewhat low-key, but in recent months attacks from IS jihadists have put forces on a state of constant high alert.

In September for instance, a roadside bombing injured six peacekeepers including four Americans.

Pentagon spokesman Navy Captain Jeff Davis said the Pentagon remains "fully committed" to the MFO mission but wants to use drones and other high-tech tools to assume some of the riskier work.

"I don't think anyone is talking about a wholesale withdrawal, I think we are just going to look at the number of people we have there and see if there are functions that can be automated," Davis said.

Defense Secretary Ash Carter and other US officials have begun "formal conversations" with Israel and Egypt, Davis added.

US officials are also considering moving some US and international troops into a camp in the southern Sinai, far from their current base -- called El-Gorah -- near the Gaza Strip.

Sinai jihadists pledged allegiance in November 2014 to IS fighters, who control parts of Iraq and Syria and also has a presence in conflict-ridden Libya.

Jihadist fighters have long used Sinai as a base and launched an insurgency after the military overthrew Egypt's Islamist president Mohamed Morsi in 2013.

Two Somalia drone strikes kill about 12 militants: US
Washington (AFP) April 12, 2016 - A pair of drone strikes in southern Somalia this week killed about a dozen Shebab militants who were threatening US and Somali forces, a US official said Tuesday.

The "self-defense strikes" were conducted Monday and Tuesday in an area north of Kismayo, Pentagon spokesman Navy Captain Jeff Davis said.

"This was in southern Somalia against al-Shebab targets that were posing an imminent threat to US (and Somali) personnel," he said.

"We think about 12 militants were killed," he added.

Calls seeking additional details from the US military's Africa Command were not immediately returned.

The Al-Qaeda-linked Shebab group was chased out of the capital Mogadishu in 2011 but remains a dangerous threat in both Somalia and neighboring Kenya where it carries out frequent attacks.

Shebab leaders have vowed to bring down the Somali government, which is supported by the international community and defended by the African Union's 22,000-strong AMISOM mission.

At least five people including two children were killed Monday in a car bomb blast outside government offices in Mogadishu.

The Pentagon last week confirmed that senior Shebab leader Hassan Ai Dhoore was killed in a drone strike.
