The European Union will Wednesday pile pressure on visiting Israeli foreign minister Tzipi Livni to re-open Gaza, so that humanitarian aid can reach Palestinians in need, said EU foreign policy chief Javier Solana, DPA reported. "It is very important that Gaza is opened. And that means opening the crossings, so that the help which the international community is willing to give can arrive to those in need," Solana said ahead of a dinner-time meeting in Brussels between Livni and EU foreign ministers. "The ceasefire is still fragile, and all efforts need to be made to ensure that it is solid, durable and sustainable," Solana said. The EU's top diplomat said the 27-member bloc was willing to do "whatever necessary" to ensure that the ceasefire is maintained, including sending monitors to a number of border crossings in the Gaza Strip. EU foreign ministers are to hold a separate talks on Sunday with representatives and top officials from Egypt, Jordan, Turkey and the Palestinian Authority.
