Israel-Hezbollah war latest: More blasts reported in Beirut after key route out of Lebanon hit by Israeli strike
The crossing into Syria was being used by thousands to flee, but the Israeli military says Hezbollah were transporting weapons along it.www.bbc.com
The US strikes reportedly hit multiple Houthi-linked sites, which included Yemen's capital Sanaa.
Houthi targets in Yemen have been struck by the US and Britain since January in response to attacks by rebels on shipping in the Red Sea and the Gulf of Aden.
The Houthis have repeatedly targeted commercial shipping in the Red Sea and Gulf of Aden since November, sinking two vessels, seizing another and causing the deaths of at least four crew members.
They've attacked around 80 commercial ships, many of them probably not doing any business with Israel.
Needless to say they are pissing a lot of people off.
