The Israeli military says a boat carrying materials for making weapons was intercepted by the navy last month en route to the Gaza Strip from the Sinai Peninsula.

It says charges against three suspected smugglers, who were detained on board, were filed this week.

The statement late Wednesday says the vessel carried material for making rockets and mortars of the type Hamas has fired at Israel.

Israel, along with Egypt, imposed a blockade on Gaza after the Palestinian militant Hamas group seized the strip in 2007 from forces loyal to Palestinian President Mahmoud Abbas. Israel says the measure is meant to stop Hamas from smuggling weapons.

Hamas brings weapons and other goods into Gaza via underground, cross-border tunnels dug to neighboring Sinai. Egypt has recently destroyed many of the tunnels.
