BAKU, March 6 (Reuters) - Azerbaijan is evacuating its diplomats from Iran for their own safety, Foreign Minister Jeyhun Bayramov said on Friday, a day after Baku said four Iranian drones had crossed its border and injured four people in the Nakhchivan exclave.

Speaking at a news conference in Baku, Bayramov said that Azerbaijan was evacuating employees from its embassy in Tehran and its consulate general in Tabriz, the largest city in Iran's northwest, where many ethnic Azerbaijanis live.

GENEVA, March 6 (Reuters) - Large-scale evacuation orders issued by the Israeli army for southern Lebanon and Beirut's southern suburbs raise serious concerns under international law, the U.N. human rights chief said on Friday.

"These blanket, massive displacement orders we are talking here about hundreds and thousands of people," said United Nations human rights chief, Volker Turk.

"This raises serious concern under international humanitarian law, and in particular when it comes to issues around forced transfer," he added.

GENEVA, March 6 (Reuters) - Key humanitarian air, sea and land routes are being constricted by disruption from the war in the Middle East, delaying life-saving shipments to some of the world's worst crises, 10 aid officials have told Reuters.

The U.S.–Israeli war on Iran entered its seventh day on Friday, convulsing global markets and disrupting supply chains with airspace closures and the halt of shipping through the critical Strait of Hormuz.

The United Nations rights chief called Friday for answers after a deadly strike on an Iranian elementary school, as a media investigation concluded the United States was most likely responsible.

On the first day of the war last Saturday, a strike hit an elementary school in the southern Iranian town of Minab and killed at least 150 people, say Iranian officials.

UN rights chief Volker Turk condemned "this absolutely tragic incident", and said he hoped investigations would be "prompt, and that they will be done in full transparency".

KABUL, March 6 (Reuters) - Pakistani and Afghan troops exchanged fire at dozens of points along their border on Friday as the U.N. said their week-old conflict has forced the displacement of more than 100,000 people.

The South Asian nations show no signs of rapprochement in their worst fighting in years, adding to the volatility in a region also contending with U.S. and Israeli strikes on Iran - a nation that borders both Afghanistan and Pakistan.

Fresh Israeli strikes on Friday battered Lebanon, where Prime Minister Nawaf Salam warned "a humanitarian disaster is looming" due to mass displacement.

An Israeli strike on an office building in the southern city of Sidon killed five people and wounded seven, the Lebanese health ministry said, as Israel presses attacks on Lebanon's south, east, and in Beirut's southern suburbs.

Speaking to foreign ambassadors, the Lebanese premier said "the consequences of this displacement, at the humanitarian and political level, may well be unprecedented".

COPENHAGEN, March 6 (Reuters) - Maersk, one of the world's biggest container shipping groups, said on Friday it has temporarily suspended two services linking the Middle East to Asia and Europe as the Iran conflict continues to disrupt global supply chains.

The Danish group said in a statement it would halt its FM1 service connecting the Far East to the Middle East and its ME11 service linking the Middle East to Europe

PARIS, March 6 (Reuters) - Around 50 French ships are currently blocked in the Persian Gulf and another eight in the Red Sea, France's Transport Minister Philippe Tabarot said on Friday, as Paris seeks support to build a coalition of countries to secure shipping traffic in the region.

"There are around fifty ships - 52 to be precise - in the Persian Gulf and eight in the Red Sea, and we are also in permanent contact with the crews, as there are French sailors aboard a number of these vessels," Tabarot told French broadcaster CNews/Europe 1.

SEOUL, March 6 (Reuters) - South Korean Foreign Minister Cho Hyun said on Friday the U.S. and South Korean militaries are discussing the possible redeployment of some U.S. Patriot missile defence systems based in South Korea to be used in the war against Iran.

Cho was responding to questions at a parliamentary hearing following media reports on Friday that units of the U.S. mobile missile interceptor system had been moved to the Osan Air Base in South Korea from other locations in the country.
