At least 9 killed, 300 wounded as Hezbollah's hand-held radios detonate across Lebanon

Hand-held radios used by Lebanon's armed group Hezbollah detonated late on Wednesday afternoon across the country's south and in the southern suburbs of the capital Beirut, a security source and a witness said.

At least nine people have been killed as per state news reports and three hundred were wounded by the new explosions. Many of the wounds were to the stomach and hands, the source said

At least one of the blasts took place near a funeral organised by Iran-backed Hezbollah for those killed the previous day when thousands of pagers used by the group exploded across the country.

The group said on Wednesday it had attacked Israeli artillery positions with rockets in the first strike at its arch-foe since pager blasts wounded thousands of its members in Lebanon and raised the prospect of a wider Middle East war.

Israel's spy agency Mossad, which has a long history of sophisticated operations on foreign soil, planted explosives inside pagers imported by Hezbollah months before Tuesday's detonations, a senior Lebanese security source and another source told Reuters.

The death toll rose to 12, including two children, Lebanese Health Minister Firass Abiad said on Wednesday. Tuesday's attack wounded nearly 3,000 people, including many of the militant group's fighters and Iran's envoy to Beirut.

A Taiwanese pager maker denied that it had produced the pager devices which exploded in an audacious attack that raised the prospect of a full-scale war between the Iran-backed Hezbollah and Israel.

Gold Apollo said the devices were made by under licence by a company called BAC, based in Hungary's capital Budapest.

There was no immediate word on when Hezbollah had launched its latest rocket attack, but normally the group announces such strikes shortly after carrying them out, suggesting it fired at the Israeli artillery positions on Wednesday.

Hezbollah has vowed to retaliate against Israel, whose military declined to comment on the blasts. The two sides have been engaged in cross-border warfare since the Gaza conflict erupted last October, fuelling fears of a wider Middle East conflict that could drag in the United States and Iran. Jordan's Foreign Minister Ayman Safadi accused Israel of pushing the Middle East to the brink of a regional war by orchestrating a dangerous escalation on many fronts.

"Hezbollah wants to avoid an all-out war. It still wants to avoid one. But given the scale, the impact on families, on civilians, there will be pressure for a stronger response," said Mohanad Hage Ali of the Carnegie Middle East Centre.

Hezbollah, Iran's most powerful proxy in the Middle East, said in a statement it would continue to support Hamas in Gaza and Israel should await a response to the pager "massacre" which left fighters and others bloodied, hospitalised or dead.
