Israel claimed Saturday that it had learned of "concrete threats" of terror attacks against Jewish or Israeli targets in Tunisia.

"Information indicates that there are plans for terrorist attacks against Israelis or Jews in Tunisia," a statement from Prime Minister Benjamin Netanyahu's office said.

The threats are connected to the Lag BaOmer Jewish festival, which will be celebrated on May 7, the statement claimed.

It urged Jews not to visit Tunisia during the festival.

Thousands of pilgrims visit the tombs of famous rabbis for Lag BaOmer, including on Tunisia's holiday island of Djerba, where one of the last Jewish communities in the Arab world still lives.

Several thousand Jews from France and Israel make the trip to the island every year, where 19 people died in an attack on the ancient El Ghriba synagogue in 2002 blamed on Al-Qaeda.
