Prime Minister Benjamin Netanyahu has laid a wreath at a memorial to Holocaust victims in Warsaw at the start of a visit to Poland.

Netanyahu met Poland's Foreign Minister Radek Sikorski on Tuesday and then visited Umschlagplatz, the spot where German Nazis in 1942 loaded about 320,000 Jews from the Warsaw Ghetto into cattle cars and sent them by train to the Treblinka death camp.

Meanwhile, President Shimon Peres is in Germany where he will address parliament to mark International Holocaust Remembrance Day on Wednesday.

Netanyahu is also to meet Poland's President Lech Kaczynski and Prime Minister Donald Tusk later in the day. On Wednesday, he is to attend observances of the 65th anniversary of the liberation of the Auschwitz-Birkenau death camp where the Nazis killed over 1 million people, mostly Jews, during World War II.

Peres, almost all of whose family was killed in the Holocaust, including his grandparents who were burned alive in a synagogue in Poland, will deliver a speech in Hebrew to the Bundestag and participated in a memorial service at 'Platform 17,' from which Berlin's Jews were sent to their death during the Second World War.

He was accompanied on his trip by survivors and their families, members of youth groups and Israel Defense Forces soldiers, who will be present at his speech and at the other events.

"The Germans have also learned a lesson," Peres told Army Radio on Monday.

"They want to mend their history, and while we can't forget we can, with them, look forward to a new future."

Foreign Minister Avigdor Lieberman was scheduled to leave Tuesday for Hungary, where he will meet the prime minister, foreign minister and other senior officials. He is scheduled to take part in a ceremony in Budapest organized by the Jewish community.

Netanyahu began the first day of his visit to Poland with political discussions with Sikorski on two matters: Iran's nuclear weapons program and the sale of Israeli weapons to the Polish army, which is fighting in Afghanistan as part of the NATO force.

It is known that Sikorski and Netanyahu agree on the need to strengthen sanctions on Iran. Netanyahu asked for Polish involvement on the matter in the European Union.

The discussion on Israeli arms sales focused mainly on unmanned drones, specifically the Hermes 450 - a matter on which the defense ministries of the two countries have already been in contact. Netanyahu and Sikorski also discussed future arm sales.

Netanyahu's first public appearance was short visit to the Warsaw Ghetto. He placed a wreath at the wall that memorializes the death of 300,000 Jews. From this site, Netanyahu was accompanied by a convoy of Polish police vehicles as well private security to the Warsaw Ghetto museum.

At both sites, Netanyahu was accompanied by his wife. She wrote in the guest book of the museum: "From Jerusalem to Warsaw and from Warsaw to Jerusalem, the people of Israel live".

Netanyahu planned an afternoon visit with Polish President Lech Kacyzski and Prime Minister Donald Tusk. Media outlets are not paying much attention to this meeting but the official ceremony to be held at Auschwitz on Wednesday will be broadcast on every Polish television channel.
