Thai authorities have issued a red alert for a potential terror attack against Israelis planning to attend the famous Full Moon Party.

The all-night beach party is popular with young Israelis and British backpackers, and takes place this Friday on Ko Pha Ngan island.

Police have bolstered their forces and stepped up security measures, erecting roadblocks across the island.

Israel's intelligence agency Mossad and the National Security Council (NSC) have warned Israelis to be on the guard throughout.

In a statement, they said: "Over recent months, Israeli security services in cooperation with Thai security have acted to thwart several incidents.

“Since October 7 and the war [in Gaza], Iran and its proxies have intensified their efforts to harm Israeli and Jewish targets around the world."

The NSC urged Israelis in Thailand to remain alert and avoid outwardly displaying their Jewish identity.

They also advised against attending large-scale events known to be associated with Israelis and to refrain from publishing their travel plans in advance on social media.

The warning applies "to the whole country, with no focus on a specific area" and comes amid allegations of an Iran-backed plot on Israeli tourists in Sri Lanka.

Israelis are increasingly being singled out for attack on their travels abroad, as public anger grows over the Gaza war.

Last Thursday, Israeli football fans were chased through Amsterdam by a violent anti-Semitic mob.

Maccabi Tel Aviv supporters were set upon by masked thugs as they left the Joan Cruyff stadium, following their team's game in UEFA's Europa League competition.

Horrifying images posted to social media channels showed the Israeli fans being kicked and beaten, as they desperately tried to flee the mob.

Victims and officials described the appalling scenes as "a pogrom" - a violent riot aimed at one ethnic group.

Dutch police arrested five more people in connection with the attacks on Tuesday, bringing the total to 68.

The five men, all from the Netherlands and aged between 18 and 37, are suspected of "public violence against persons" before and after the Maccabi Tel Aviv match against Ajax.
