An immigrant rescue boat defied Italy's ban and docked at Lampedusa overnight, but none of the 41 people saved from the Meditarranean Sea have been allowed to disembark.  Alex is run by the charity "Mediterranea" charity,  which says Italy's draconian anti-migrant policy is "an unnecessary cruelty".  Another rescue ship - the Alan Kurdi, named for the Syrian toddler who died on a Turkish beach in 2015 - is waiting in international waters just outside Lampedusa, carrying another 65 people.

If this wasn't the Fourth of July holiday weekend in the US, an explosion that tore through a Florida shopping center likely would have been much, much worse.  The blast in the Miami/Fort Lauderdale suburb of Plantation leveled a Pizza restaurant under construction and a computer coding school for kids aged 7 to 14 years old - luckily, they were off for the Independence Day weekend.  A health club across the aisle was heavily damaged and dozens of cars in the lot were rendered undriveable.  At least 22 people were injured.

Across the US in Southern California, a second major earthquake rocked the desert northeast of Los Angeles.  Friday night's magnitude 7.1 temblor - felt in Los Angeles, Las Vegas, and Arizona -  was eleven times stronger than the 6.4 the day before, which was Cali's strongest in around 25 years.  There is a visible faultline ripped through the desert, but physical damage is limited to a few mobile homes that weren't secure on their foundations and a lot of glass jars of stuff that fell off of shelves at supermarkets.  Several people were injured, but no fatalities are reported.

Botswana's government will appeal against last month's historic Supreme Court ruling that wiped-out colonial-era laws that imposed up to seven year jail terms for same-sex relationships, saying they were unconstitutional.  Attorney General Abraham Keetshabe claimed the justices erred making the decision, but couldn't say why or how.  Angola, Mozambique and the Seychelles have all scrapped anti-homosexuality laws in recent years.
