Lebanese Prime Minister Nawaf Salam declared Thursday a national day of mourning after Israeli strikes pummelled the country, killing at least 182 people and wounding 890, according to the health ministry.

The strikes were Israel's heaviest on neighboring Lebanon -- including in densely packed central Beirut -- since the Iran-backed militant group Hezbollah joined the war in early March.

WASHINGTON/DUBAI/CAIRO, April 8 (Reuters) - U.S. President Donald Trump agreed to a two-week ceasefire with Iran on Tuesday, less than two hours before his deadline for Tehran to reopen the Strait of Hormuz or face devastating attacks on its civilian infrastructure.

April 8 (Reuters) - U.S. President Donald Trump said on Wednesday the United States will help with the traffic buildup in the Strait of Hormuz.

"We'll be loading up with supplies of all kinds, and just 'hangin' around' in order to make sure that everything goes well," Trump said.

"There will be lots of positive action! Big money will be made. Iran can start the reconstruction process," he also said.

The United States and Iran agreed to a two-week ceasefire, with both sides claiming victory.

Here are reactions from across the globe:

Pakistani Prime Minister Shehbaz Sharif, having earlier welcomed the ceasefire, said violations between the United States and Iran had already reported.

SYDNEY, April 8 (Reuters) - Australian Prime Minister Anthony Albanese on Wednesday welcomed a ceasefire in the Middle East struck between the U.S., Israel and Iran, while criticising the rhetoric of President Donald Trump.

President Donald Trump told AFP on Tuesday that the United States had won a "total and complete victory" after agreeing a two-week ceasefire deal with Iran.

In a telephone call, Trump said he believed China had persuaded Iran to negotiate, and said Tehran's enriched uranium would be "perfectly taken care of."

The US leader appeared bullish on the truce with Iran, despite Tehran also casting it as a win for its side, and amid questions over exactly what both sides had agreed on.

Oil and gas prices plunged, stock markets soared and the dollar retreated Wednesday after the United States and Iran agreed to a temporary ceasefire that could lead to the Strait of Hormuz reopening.

"A wave of relief has hit financial markets after threats of a devastating escalation of the war were replaced by a temporary truce," said Susannah Streeter, chief investment strategist at Wealth Club.

The most widely traded oil contracts fell some 15 percent to around $95 a barrel, after more than a month of conflict that killed thousands and hammered global markets.
