- Israel's military actions in Gaza and Lebanon face international condemnation
Demonstrations were held in major cities from Jakarta to Istanbul to Rabat, and followed protests on Saturday in major European capitals as well as Washington and New York.
"We are here to support the Palestinian resistance," said protester Ahmet Unal in Istanbul, where thousands assembled.
On October 7 last year, Hamas attacked southern Israeli communities, killing 1,200 people and taking about 250 hostages, according to Israeli figures.
Israel's subsequent military campaign against Hamas in Gaza has killed nearly 42,000 Palestinians, according to Gaza's health ministry, and laid waste to the enclave.
Israel launched air attacks on Beirut's southern suburbs overnight and early on Sunday, the most intense bombardment of the Lebanese capital since Israel sharply escalated its campaign against Iranian-backed group Hezbollah last month.
In Jakarta, the capital of Indonesia at least 1,000 pro-Palestinian protesters gathered on Sunday morning near the US embassy demanding that Washington stop supplying weapons to Israel.
In Sydney, thousands of pro-Palestinian protesters gathered ahead of the Oct. 7 anniversary, chanting and waving Lebanese and Palestinian flags amid a heavy police presence.
One person was arrested for waving an Israeli flag with a swastika in the middle of it instead of the Star of David.
In Rabat, thousands of Moroccans marched, calling for a halt to the violence in Gaza and Lebanon, in one of the largest protests in the country since the beginning of the war in Gaza.
Protesters demanded an end to Morocco's diplomatic ties with Israel, chanting "no to normalisation, Palestine is not for sale," referring to Morocco's establishing of diplomatic relations with Israel.
Over the past year, the scale of the killing and destruction in Gaza has prompted some of the biggest global demonstrations in years, including in the US, which saw weeks of pro-Palestinian college campus encampments.
Israel has faced wide international condemnation over its actions in Gaza, and now over its bombarding of Lebanon.
