The Luxembourg government has issued travel advice due to the escalating conflict between Israel and Gaza, as fighting with Hamas left hundreds dead on both sides over the weekend.

Luxembourgers currently in the region should stay safe and take advice from local authorities, the Ministry of Foreign Affairs said on Sunday.

In a statement, the foreign ministry said "The Luxembourg government strongly advises its nationals against any travel to Israel and the region." It also warned of potential air traffic disruption as the situation develops.

In addition, the ministry recommends that those who have not yet registered on the platform LamA - Luxembourgers abroad - should do so and report their presence to the consular advice of the Ministry by email at the following address:

The conflict's bloodiest escalation in decades saw Hamas carry out a massive rocket barrage and ground, air and sea offensive Saturday that Israel's army said had killed more than 200 Israelis and wounded 1,000, while soldiers and civilians were taken hostage.

Gaza officials said intense Israeli air strikes on the coastal enclave had brought the Palestinian death toll to at least 256, with nearly 1,788 wounded.

As fighting raged Sunday, Lebanon's powerful Iran-backed Hezbollah movement said it had fired "large numbers of artillery shells and guided missiles" at Israeli positions in a contested border areas "in solidarity" with Hamas.

According the the foreign ministry 35 Luxembourg residents are currently in Israel.
