'US evaluating the possibility of dropping aid into Gaza from planes' 'The situation is really serious. We need extreme measures like airdrops,' one of the sources said.

Officials admit, airborne aid is limited because a military jet can only drop an amount of supplies equivalent to that carried by one or two trucks. They can be used in case of emergency but, the sources underline, the only way to send assistance to Gaza is by land. The White House has not commented on the report.
