Amid fears of an expanding war in the Middle East following mass detentions of bombs surreptitiously planted in Hezbollah communication devices, Israel continued its assault of the Iran-backed militia overnight.

Iran's ambassador to Lebanon, Mojtaba Amani, was slightly injured on Tuesday by the explosion of an electronic pager, Iran's semi-official Fars news agency reported, as numerous such devices exploded across Lebanon.

Lebanon’s death toll from a series of walkie-talkie and pager explosions this week rose to 37, according to local authorities, an illustration of the devastation wrought by a wave of suspected Israeli attacks aimed at Hezbollah militants.
