Israel has launched fresh strikes in Lebanon, a day after it carried out an air strike in the capital Beirut that killed 37 people, including three children. 


Apart from launching an offensive, Israel has also restricted gatherings in the city of Haifa and other northern areas as it continues to attack targets linked to Hezbollah, reported BBC.  


Dozens of fighter jets started "extensively" striking southern Lebanon "following detection of Hezbollah preparing to fire toward Israeli territory", Israel Defense Forces (IDF) spokesman Rear Adm Daniel Hagari said.
